Queries

Reference only one InfoCube

No limitation to the number of queries per InfoCube

Extract data from an InfoCube based on a selection of

characteristics and key figures

Can contain global variables, restrictions, formulas andstructures

Allow creation of new local restrictions, formulas and structures

Contain drag and drop features – lets user organize

characteristic and key figures to define report Are displayed within a workbook

Query Contents (continued)

All characteristics and key figures contained in anInfoCube are listed in Pane 1

Contains characteristics that will be displayed in

the report (Shown on the vertical axis)

Contains key figures and characteristics (Shown onthe horizontal axis)

Additional characteristics are contained in this

area. They are not initially displayed in the report,

Three types of key figures

Basic – Data directly from the cube Calculated - A value determined by a formula

Restricted - Restricts the value of a basic key figure by

characteristic (Example: Expense for the first two months

of the year)

Rows, Columns, & Report Format (Panes 2, 3, & 6)

Key figures & characteristics (pane 1)are placed in rows (pane 2)

and columns (pane 3)

Query developer can see what report

will look like (pane 6) prior to running

As changes are made to contents of rows and

columns, the report format reflects those changes

Contain the fields that appear in

the ‘Navigation Block’ of the workbook

Are available for drill down which will

cause them to be included in the report

Once added, report may be sorted, filtered,

arranged etc. by the free characteristic

Filters (Pane 5)

Provide a method to restrict datain the query

Characteristics and key figures

may be used as filters

Values or variables can beassigned as a filter

Query will retrieve only data that is specified in the

filter value or variable

Filter value: Hard coded in the query – not available for userinput

Filter variable: Available for user input on the selection screen

Build a Query

Identify required data for report

Select the InfoCube that contains the required data

Queries can only extract data from a single InfoCube

Add characteristics and key figures to query




Selecting a Cube

Click the ‘Open’ icon on the Business Analyzer

toolbar

Expand ‘Dimensions’ to see available

characteristics

Dimensions logically organize characteristics

Characteristics are used in the queryDimension

Expand ‘Key Figures’ to display available basic,

restricted and calculated key figures

All 3 types not available in every cube

Restricted Key

Basic Key Figures





Building a Simple Query

Drag and drop characteristics and key figures into

(or out of) your query

Key figures / characteristics can be placed in either columns or

rows





Building a Simple Query (cont)

Selection of key figures creates a local ‘structure’

Structure keeps key figures together when

building more detail in the query

navigating within a workbook

Key Figure Structure





Building a Query (cont)

Format pane displays preview of report layout

Report Layout





Group Discussion

How do you know what InfoCube to select whenbuilding a query?

Do key figures go in rows or columns? How about

characteristics?

What is the purpose of a local structure?





Save the Query

Save the query by selecting the save iconon the query designer toolbar

A pop-up box appears – provide the query with both

a descriptive and a technical name

Technical Name

Descriptive Name





Query Names Technical Names

Must be unique

Should always include the source cube technical name

Must contain query prefix

‘X’ = Power user ad-hoc queries

‘Y’ = Power user queries for multiple end users

Cannot contain dashes (-), but can contain underscores (_)

Descriptive Names
