Unit 1: Introduction PLM220
Lesson: Project Structures
Lesson OverviewIn this lesson, you will learn about the various options for editing project structures
You will create a project for producing a turbine using the Project Builder. You will
also be introduced to Claim Management.
Lesson Objectives
After completing this lesson, you will be able to:
Create project structures consisting of WBS elements and activities in the Project
Builder
Business Example
Your company produces turbines. It has become evident that these turbines are
too complex to produce using production orders. As an alternative, you use WBS
elements and activities in the Project System.

PLM220 Lesson: Project Structures
The slide shows the project that is used as an example in the course. No logistics
aspects other than dates are treated at WBS element level. The logistics aspects of the
project - internal and external services and material requirements for example - are
planned and executed using activities.
The icons in the slides correspond to those used in the SAP system for project
definition, WBS elements, network headers, activities and relationships. You will find
them in all transactions in the project system.
Figure2: Work Breakdown Structure: Functions
The work breakdown structure (WBS) forms the basis for all other planning steps in
the project. The emphasis is on planning, analysis, description, control and monitoring
of costs, basic dates and budget.
Costs, dates and payments are frequently planned using activities that are assigned
to WBS elements.

Unit 1: Introduction PLM220
Figure 3: Work Breakdown Structure: Maintenance Options
You can use the Project Builder to create and change WBS elements.
You can use the detail screens or the WBS element overview list for this purpose.
You can use the hierarchy graphic to change WBS elements (by double-clicking on
a WBS element in the graphic). You can also create new WBS elements and insert
these into the hierarchy (connect mode).
In addition to manual maintenance or maintenance via the hierarchy graphic (1, 2), youcan also use existing project structures or standard projects as templates to copy from.
When you create a new WBS, you can use an existing WBS, a section of the project
hierarchy or a standard WBS as a template to copy from. You can also incorporate
WBS elements from other projects or from a standard WBS in an existing work
breakdown structure (3, 4).

PLM220 Lesson: Project Structures
Figure 4: Project Builder
The Project Builder is a feature in the Project System that is particularly intuitive
and easy to use.
In the Project Builder, you can create or edit WBS structures or networks individually
or in an integrated manner. To maintain WBS structures and networks, you can
navigate quickly and efficiently in the Project Builder, between the various views
(detail and overviews), graphics, and the project planning board. This unit and the
subsequent units of the course will familiarize you with the functionality of the Project
Builder.
The Project Builder consists of a processing screen divided into three parts
- the structure overview at the top left, the work list at the bottom left and a
display/processing area to the right.

Figure 5: Activities and Networks: Functions
You use the activities in the network to plan the labor, capacities, materials, and
services that you require to carry out the various tasks in your project.
The unit on capacities discusses internally-processed activities in detail.
The unit on external activities deals with externally-processed activities and service
activities.
The unit on materials explains how material components are assigned, procured and
consumed in the network.

Figure 6: Activities: Maintenance Options
In addition to maintaining data manually or via the network graphic (1, 2), you can
use existing operative structures or standard structures as templates.
When you create activities, you can use a standard network or an existing network as a
template (3). You can also incorporate standard networks into an existing network (4).
You can use the Project Builder or the project planning board to copy a standard
project or operative project (including all activities) to a new project structure (5).

Unit 1: Introduction PLM220
Figure 7: Network Graphic
The network graphic provides all of the functions needed to process a network (the
functions for inserting activities or relationships, for example).
You can call up the network graphic from various transactions in the Project
System, for example in network maintenance, scheduling and in the Structure/Dates
Information System.
The cycle analysis is a function that you can only perform in the network graphic. A
cycle is a closed sequence of relationships and activities ("closed" means that when
you start out from one activity, you end up back at the same activity by means ofrelationships). If the activity-relationship-activity path is cyclical, you will not be able
to schedule the network. Cycle analysis is a tool that enables you to detect cyclical
relationships and correct them.

Figure 8: Project Planning Board
The project planning board is particularly suitable for planning a project. It provides
you with an instant overview of your project deadlines, enabling you to check your
project for capacity bottlenecks. Additional options are also available for enhancing
your project structure. In the following units, you will use both the Project Builder
and the project planning board to edit your project.

Claim Management
Figure 9: Claim
Deviations from the project plan often occur as a result of delivery problems, price
fluctuations, unforeseeable capacity bottlenecks and so on. In this case, clarifying
responsibilities is extremely important for the contractual partners involved. Claim
Management ensures that claims resulting from deviations are prepared vis--visthe contractual partner and submitted at a suitable point in time. Conversely, it also
provides defence against claims from the contractual partner. The Project System
supports claim management with the "Claim" message type, which can be used to
document deviations from your project plan, appoint persons responsible for the
deviation and initiate follow-up activities.
You can enter claims directly in the SAP system or create and display them from the
Internet (for example: a customer creates a claim over the Internet).

You can include the following data in a claim:
Descriptions - the cause of the deviation for example
Actions and tasks to be initiated because of the deviation Persons responsible and partners by means of a link to the Partner Management
function
Costs incurred as a result of the deviation (cost planning using unit costing)
Assigned WBS elements, SD and MM document items
Assigned document info records (links to the Document Management System)

PLM220 Lesson: Time Scheduling with WBS Elements
The following functions are available to you:
Sets of dates: Basic and forecast dates can be used as planned dates. Actual dates
are also shown here. Check dates: You can check consistency of the dates within the project structure
with or without taking activities into account.
Inherit: Dates within the WBS can be inherited.
Extrapolate: You can use the extrapolate function to calculate the dates for
higher-level WBS elements.
Shift: You can shift all of the planned dates for the WBS elements or just the
dates in subhierarchies.
Planning different calendars: You can use a different factory calendar for each
activity or WBS element.
Scheduling: The scheduling function calculates the dates for activities and
networks.
Planning form: You can use the planning form to extrapolate dates automatically
- for example, when you save your data.

Basic Date Planning with WBS Elements
Figure 12: Basic Dates WBS
In projects without networks, dates can be planned manually for the WBS elements
(basic dates).
You can use the project planning board to plan basic dates for the WBS elements
simply by dragging your mouse. You can plan these dates in the form of a table in
Structure Planning.
Basic dates can be extrapolated from lower to higher-level WBS elements or,conversely, inherited from higher to lower-level WBS elements. You can check the
consistency of your scheduling data within the WBS structure.
In the execution phase, you can enter actual dates by dragging your mouse. In the
project planning board or the information system, you can compare the actual dates
with the planned basic dates.

Figure 14: Scheduling
Each time a network is scheduled, the system carries out forward and backward
scheduling; determines floats and capacity requirements (if activated).
Forward scheduling determines the earliest dates.
Backward scheduling determines the latest dates.
Floats occur if the earliest dates are different from the latest dates.
The scheduling results:
Scheduled start and finish for the network header
Earliest start and finish dates (earliest dates) and latest start and finish dates
(latest dates) for the activities

Figure 15: WBS / Overall Network Scheduling
You can schedule networks individually (network scheduling). You can schedule all
networks linked by relationships together (scheduling of overall network). You can
also trigger network scheduling from WBS elements (WBS scheduling).
The activity data, relationships between the activities and date restrictions form the
basis for determining dates automatically (scheduling).
As of Release 4.6A you can schedule maintenance orders from the Project System.
In theProject Schedulingand Overall Network Schedulingtransactions, you can
specify whether networks are scheduled together with maintenance orders that have
been assigned as subnetworks.
You can display an overview of the maintenance orders assigned to a project in the
project planning board.

Scheduling Scenarios
Figure 16: Bottom-Up Scenario
In projects with assigned networks, you can use scheduling to derive the dates of the
activities and WBS elements automatically.
Using the project planning board, you can select WBS elements and schedule the
activities assigned to them. The scheduling parameters determine how the activities
are scheduled.
Networks are always scheduled forwards and backwards. The scheduling type
determines the original direction in which scheduling is carried out. The system
determines the earliest dates of the activities by means of forward scheduling and
the latest dates by backward scheduling.
The differences between the earliest and latest dates of an activity are referred to as
floats. If these are less than or equal to zero, the activity is termed critical.
The dates of the assigned activities are summarized to give the scheduled dates of the
WBS elements (thin time bars in the project planning board).
The dates scheduled in the WBS structure can be copied to the basic dates of the WBS
elements for the purpose of extrapolating them up the project hierarchy.

Customizing in Time Scheduling
Figure 19: Customizing for Scheduling 1
Scheduling types are used both for network scheduling and for WBS scheduling. The
indicators have the following meanings: Forward: Forward scheduling is carried out
first, followed by backward scheduling. Backward: Backward scheduling is carried
out first, followed by forward scheduling. Cap.requirements only: No scheduling is
carried out at all. Instead, the start and finish dates of the network header are copiedto each activity. Todays date: Backward scheduling is carried out first, followed by
forward scheduling starting from todays date. Basic dates with times: This indicator
is notrelevant for networks.
Scheduling parameters are created for specific plants and network types. The
scheduling parameters determine scheduling, for example, in the transactions network
maintenance (CN22) and scheduling of the overall network (CN24). The indicators
have the following meanings: Adjust basic dates: Determines that the scheduled dates
are copied to the basic dates of the network header after a scheduling run. The settings
for secondary requirements do not have any impact in the network. Scheduling type:
Determines the type of scheduling - for example, forward first, then backward. Start
in the past: Determines how long ago (in days) the start date can be. If it is more than
the specified number of days, scheduling is carried out for todays date. Automatic
scheduling: Scheduling is carried out on saving. Log automatic: If a log is generated,
it is displayed automatically. Break spec. scheduling: The exact time at which a break
is scheduled (in the work center) is taken into account. Shift order: Determines how

the system deals with partially-confirmed activities during scheduling (see below).
Latest material dates: The requirements dates for a material are determined based on
the earliest or latest date. Reduction type: Either all activities or only those along
the critical path are reduced. Maximum reduction level: A reduction strategy canhave up to six levels. The highest level of reduction is specified here. Rescheduling:
Determines how the system deals with work allocated in workforce planning after
another scheduling run has been carried out.
Figure 20: Customizing for Scheduling 2
The profile for WBS scheduling is used for scheduling in the project planning board
transaction CJ2B or in the project scheduling transaction (CJ29).
The indicators have the following meanings: Scheduling type: Determines the type of
scheduling, for example, forward first, then backward. Start in the past: Determineshow long ago (in days) the start date can be. If it is more than the specified number of
days, scheduling is carried out for todays date. Scheduling form: Specifies which
object - network header or WBS element - is used as a basis for scheduling. Adjust
basic dates: Determines that the scheduled dates are copied to the basic dates of
the WBS elements after a scheduling run. Log automatic: If a log is generated,
it is displayed automatically. Shift order: Determines how the system deals with
partially-confirmed activities during scheduling (see below). Schedule when saving:
Scheduling is carried out on saving. Latest material dates: The requirements dates
for a material are determined based on the earliest or latest date. Maximum reduction
level: A reduction strategy can have up to six levels. The highest level of reduction is
specified here. Reduction type: Either all activities or only those along the critical
path are reduced.
The WBS scheduling profile is stored in the project definition control data. It can
be copied as a default value from the project profile. One (or neither) of the two
scheduling scenarios is displayed by default in the project profile.

Other Influencing Factors in Scheduling
Figure 21: Scheduling: Duration
When scheduling internally-processed activities and general costs activities, the
system uses the normal duration you maintained in the activity. The duration can be
calculated from the work planned, provided you have stored a formula for calculating
the duration from internal processing in the work center.
When scheduling externally-processed activities, the system uses the number ofplanned delivery days you maintained for an external activity. You can, however, also
use the normal duration from the internal processing screen of the external activity if
you activate this explicitly in the control key of the external activity.
Scheduling interprets the time interval for relationships as the minimum time interval.
When calculating the dates, scheduling can increase the time interval but not reduce it.
You can maintain a work center in internally and externally processed activities and in
relationships. The following information is stored for scheduling in the work center:
Formulas for calculating the duration of activities.
A factory calendar and the operating time for each workday.

control key indicators function as follows: Schedule: Activities and activity elements
are scheduled. For activity elements, the dates for the activity are determined. Det.
cap. req.: Capacity requirements are determined for activities and activity elements.
The capacity requirements are determined using the scheduling results. Therefore,
only set this indicator if you also set the scheduling indicator. Costs act.: This
indicator specifies that you use the control key for general costs activities. Costing:
This indicator determines that activities and activity elements are taken into account in
costing.Print time ticket: This determines whether time tickets can be printed. Time
tickets are only printed if thePrint indicator is also selected. For information on
further relationships, see the online help. Confirmation: Determines whether activities
and activity elements can be confirmed. External proc.: Determines whether activitiesand activity elements are processed internally or externally. Service: Determines
whether services can be planned for activities and activity elements. Only set this
indicator if you select the External proc. indicator to allow external processing.
Print conf.: This determines whether completion confirmation slips can be printed.
Completion confirmation slips are only printed if thePrintindicator is also selected.
For information on further relationships, see the online help. Print: Determines
whether work papers such as time tickets, completion confirmation slips can be
printed. For information on other relationships, see the online help. Sch.ext.proc.:

PLM220 Lesson: Scheduling of Activities and Networks
Scheduling Example
Figure 24: Example of Scheduling
A network is always scheduled forwards and backwards. The scheduling type
specifies whether forward scheduling or backward scheduling is carried out first.
Forward scheduling calculates the earliest start and finish dates for the activities.
All activities that do not have predecessors are start activities. The scheduling start
start date is the start date in the network header or the start date determined from
backward scheduling.Backward scheduling calculates the latest start and finish dates for all the activities.
Target activities are network activities that do not have successors. The scheduling
start date is the finish date in the network header or the finish date determined from
forward scheduling.
In the example above, the start dates are set to the beginning of the day (00:00) and the
finish dates to the end of the day (24:00). If work centers are entered for the activities,
the start and finish dates are within the operating time of the work centers affected.

Figure 25: Total Float, Free Float
Legend:
ES= Earliest Start EF= Earliest Finish
LS= Latest Start LF= Latest Finish
TF= Total Float FF= FreeFloat
Floats supply information on the time reserves available for individual activities. Youcan use the floats calculated in scheduling, for example in capacity leveling, to shift
activities between the earliest and latest dates or to extend their duration.
A total float is the difference between the latest start and earliest start (LS - ES) or
between latest finish and earliest finish (LF - EF).
A free float is the difference between the earliest start of a successor activity and
the earliest finish of the activity in question (ES successor - EF activity). Since the
successors for the free float are within their earliest dates, the time reserve is fully
available to the current activity.

Day 6 (0:00) - Day 5 (0:00) = 1 day.
The free float of activity 40 can be calculated from the difference between the earliest
start of the successor (activity 50) and the earliest finish of the activity.

PLM220 Lesson: Scheduling of Activities and Networks
Figure 28: Reduction
You can use reduction if the time period within which the activities are to be scheduled
is not long enough to process all activities. This allows you to reduce the scheduled
duration of internally-processed activities.
Reduction only affects the activities for which a reduction strategy has been stored.
At the most, the system reduces as far as the level of reduction strategy entered
in the network header.
During scheduling, the system determines one reduction level for each activity. For
example: The system calculates the earliest dates and determines reduction level 2 for
an activity. This reduction level is transferred to the latest dates.
Important: Remember to be careful when using the reduction function as the system
does not know whether the duration of an activity can be reduced. It does not carry
out plausibility checks or check available capacities.
You can use reduction strategies to control how an activitys lead time can be reduced
in levels. You can enter a reduction strategy in each activity.
You can define up to six reduction levels for each reduction strategy. You can enter by
what percent you want to reduce for each reduction level.

Scheduling of the Overall Network
Figure 29: Scheduling of the Overall Network
The confirmed delivery date of an item in the sales order corresponds to the finish
date of the assigned network. If the end of a network is shifted because of scheduling
problems, the confirmed delivery date in the sales order is changed automatically. You
can, however, also fix a confirmed delivery date for the item on the Schedule lines
tab page.
As of Release 4.0, scheduling of the overall network for the sales order item can be
started in the sales order itself.
This function schedules both the network assigned to the sales order item and all other
networks linked to this network via a relationship.
This function updates all items in the sales order that refer to the overall network.

Figure 30: Overall Network Scheduling with Selection Options
As well as overall network scheduling (transaction CN24), which you can use to
schedule several networks and subnetworks together, you also have at your disposal,
from ECC 5.0 onwards, the new functionoverall network scheduling with selection
options(transaction CN24N).
You use this function along with suitable selection criteria to specify which networks
and subnetworks are to be taken into account as part of overall network scheduling.
You can display additional information on the selected activities and subnetworks on a
monitor and jump to the next screen to processing or confirmation of activities.
A prerequisite for the use of theOverall network scheduling with selection options
function is that you have defined suitable levels beforehand in Customizing for the
project system and have assigned network types and number intervals. Note that
you can only schedule using two levels.
By using a BAdI forOverall scheduling with selection options, you have other
functions at your disposal such as control of data exchange between activities and
assigned subnetworks.

Figure 33: Requirements Date: Material
The system calculates the requirements date for components with reference to the start
or finish date of the activity. You can use the Scheduling parameters for network type
or theParameters for WBS schedulingto control whether the earliest or latest start
date is used as the requirements date. The transaction used to trigger the scheduling
determines which of the two tables is used. If you schedule within the network or
the overall network, theScheduling parameters for the network type apply. If you
schedule within the project planning board or using structure planning, the Parameters
for WBS schedulingapply.
If the requirements date is before the finish date of the activity, you can store a
corresponding time interval by using an offset to the finish date.
You can also set a requirements date for a material manually.

Exercise 2: Scheduling
Exercise ObjectivesAfter completing this exercise, you will be able to:
Carry out time scheduling with predefined scenarios
Use relationships and restrictions
Business Example
Using the project planning board, you calculate the dates and floats for carrying out
the individual activities of your turbine project. At the same time, you also take into
account the time-based dependencies of the individual activities and, if necessary,
other conditions.
Task 1:
1. Call up the project planning board.
2. Process your project T-100## in the project planning board. Use the1001
Elevators/Turbinesplanning board profile.
3. Optimize the project display to show all activities completely.
4. Plan dates for your project using the predefined bottom-up scenario.
First check the time scheduling settings.
Set the scheduling scenario to Bottom-up scenario (pre-defined) if you have
not already done so.
Plan the dates for the entire project.
Hint: The bottom-up scheduling scenario is set so that all activity
dates are determined and then the earliest and latest dates for each
are transferred to the assigned WBS elements. To finish, dates are
extrapolated for upper-level WBS elements within the hierarchy.

Unit 2: Dates PLM220
5. Check the floats for your project. Display both the earliest and the latest dates.
Hint: Scheduling always calculates the dates of activities forwards andbackwards. Each activity (and activity element) thus has two time bars.
Different colors (usually blue and red) are used to distinguish between
activities in the planning board that still have or no longer have time
floats.
6. Change the duration of activity 4000Production of running gear, bearing, valves
and look at the effect this has on scheduling.
Reduce the duration of the activity to 30 days.
Hint: Although the system adjusts the time bars of activity 4000 in the
graphic, the overall project dates are no longer up to date. You need to
perform scheduling again. Note the changes to activities 3000 and 3100.
How are activities 3000 and 3100 affected?
7. Save your scheduling data.
Task 2:
1. Now take a look at the scheduling details. Once again, use the project planning
board for this purpose. Call up your project.
2. Create two further activities within activity 5010Planning of instrumentation.
The activities will be linked to each other at a later stage.
3. Input the details for the two new activities.
Enter the following data in the detail screen for activity 5020:
Field Name Values

Plan the dates for the entire project.
Hint: The bottom-up scheduling scenario is set so that all activitydates are determined and then the earliest and latest dates for each
are transferred to the assigned WBS elements. To finish, dates are
extrapolated for upper-level WBS elements within the hierarchy.
a) First check the time scheduling settings.
ChooseOptions.
Set the scheduling scenario toBottom-up scenario (pre-defined).
Confirm your entries by clicking the Copypushbutton.
Plan the dates for the entire project.
ChooseSelect allto select all objects.
Start the scheduling procedure by clicking the appropriate icon.
5. Check the floats for your project. Display both the earliest and the latest dates.
Hint: Scheduling always calculates the dates of activities forwards and
backwards. Each activity (and activity element) thus has two time bars.
Different colors (usually blue and red) are used to distinguish between
activities in the planning board that still have or no longer have time
floats.
a) ChooseSet of Dates/View.
Activate theLatest dateindicator and confirm your data entries by clicking

The extended duration of the activity affects the entire network.
Previously, activity 3000 was critical (it had negative floats). After
scheduling, it has positive floats. Activity 3100 behaves in a completely
different way. In the network structure graphic, you can see that theactivities lie in two different, parallel paths. Before scheduling, the
first path (with activity 3000) is the critical path in the network. After
scheduling, the other path (with activity 3100) represents the critical path.
7. Save your scheduling data.

Why does activity 5010 have a free float?
a) ChooseSelect allto select all objects.
Start the scheduling procedure by clicking the appropriate icon.
Note the free float in the detail screen of activity 5010.
The free float is the difference between the earliest finish date for an
activity and the earliest start date for the successor. The earliest start for
the successor was only set to a later date by restricting the start date of the
successor (5020, Cannot start before). Free floats also appear for parallel
activities that have the same successor. In this case, the longer activity
determines the earliest start date of the successor and the shorter activity
has a free float.

Lesson: Actual Dates
Lesson OverviewThis unit deals with the various ways of entering actual dates for WBS elements and
activities. At the same time, prerequisites for entering actual dates are discussed as
well as the effect of actual dates on subsequent scheduling runs.
Lesson Objectives
After completing this lesson, you will be able to:
Enter actual dates for WBS elements and activities
Business Example
You want to compare planned dates with the actual execution dates in the execution
phase of your project in order to be able to monitor the date situation for your project.
To do this, you enter the actual dates for your project.
Entering Actual Dates
Figure 35: Actual Dates
To monitor the dates for a project, you compare the basic dates with the actual dates
or forecast dates.

PLM220 Lesson: Actual Dates
Actual dates can be set manually for WBS elements. If you are using network
activities, actual dates are set by confirming activities. If activities are assigned to
a WBS element, the actual dates of the activities are proposed to the WBS element
as provisional dates that can be transferred to the actual dates of the WBS elementif necessary.
Important: Actual dates are usually updated for an activity during activity
confirmation. You can suppress this update if necessary. To do this, select the No
date updateindicator during confirmation.
Actual Dates of WBS Elements
Figure 36: Actual WBS Dates
Legend:
AS = Actual start date AF= Actual finish date
CNF= Finally confirmed REL= Released
For WBS elements without assigned activities:
You can always maintain the actual start if the WBS element has the status
Released or Partially released.
You can only maintain the actual finish if all lower-level WBS elements have
an actual finish date.

Unit 2: Dates PLM220
The following also applies to WBS elements to which activities are assigned:
You can only maintain the actual start if the assigned activity has the status
Partially released or Released. You can only maintain the actual finish date if all the lower-level WBS elements
also have an actual finish date and all the activities for the WBS element have
the status Finally confirmed.
Actual Dates of Activities
Figure 37: Actual Dates of Activities
Actual dates are entered in networks using confirmation. This can be carried out using
individual or collective confirmation, or the cross application time sheet.
Once an activity has been finally confirmed, the start and finish of the earliest and
latest dates match the actual start and actual finish dates.
Partial confirmations affect the scheduling result for the earliest date in accordance
with the Shift order indicator.
The Shift order indicator is not set: The actual start date and forecast duration
of the partial confirmation are taken into account when the earliest date is
calculated. The Shift order indicator is set: The actual start date of the partial confirmation
is not taken into account when the earliest date is calculated.

Exercise 3: Actual Dates from Confirmations
Exercise ObjectivesAfter completing this exercise, you will be able to:
Describe the effects of actual dates on time scheduling
Business Example
You create partial confirmations for activities that are already being processed and
calculate the resulting shifts in dates for your project.
Task:
1. So far, you have planned dates but not begun to enter actual dates. Actual dates,
however, can also affect your planned dates. Take a look at how actual dates
affect planned dates in the project planning board. To do this, start by opening
your project in the project planning board and alter the display accordingly.
2. Before you start to enter actual dates, transfer the dates planned previously (basic
dates) to the set of dates for alternative time scheduling (forecast dates).
Show the forecast dates, compare them with the basic dates, and then hide
them again.
Hint: Forecast dates can be determined via scheduling in the sameway as basic dates. These dates are simply alternative dates for time
scheduling and are used in the course to freeze time scheduling at a
certain point in time. This allows comparisons to be made with changed
time scheduling (basic dates) at a later stage.
3. Before you can enter actual data, you have to release activities or WBS elements.
Release the WBS element T 100##.1Engineering and Design.
The status is inherited to lower-level activities to allow you to continue entering
actual activity data.
4. Enter a partial confirmation for the activity 1000Engineering of
drawing/calculation/design. Display both the actual dates and the basic dates inthe diagram area.
Enter the following data in the confirmation dialog window:

scheduling. Activate this indicator and carry out the scheduling process again.
Except for theShift orderindicator, the settings for the predefined profileIDES
scheduling forwardcorrespond to the bottom-up scenario.
Reschedule your project.
Notice how the time bar of activity 1000 becomes shorter and the dates of all
following activities are adjusted.
7. Compare the basic dates with the forecast dates.
Hide the forecast and actual dates again.
8. Select the bottom-up scheduling scenario again.
9. Save the changes to your time scheduling settings.
