3 What Well Cover SAP NetWeaver Visual Composer overview Building an SAP NetWeaver Visual Composer model Demo A cockpit in 8 minutes Improving performance tuning Mapping the future of SAP NetWeaver Visual Composer 7.0 Looking at other options Wrap-up

4 SAP BI is an enterprise-wide comprehensive decision support system (DSS) for the analytical needs of an enterprise BI can also support some degree of operational reporting The SAP BI tool set has many presentation tools and options for companies to leverage. SAP NetWeaver Visual Composer is an extension of those tools. The SAP NetWeaver BI Core Toolset

5 Visual Composer 7.0 is for SAP BI Development, 7.1 is for the Composite Environment (CE). There are different SDN forums and blogs for each - This can be confusing! BREAKING NEWS: VC 7.2 is now in Ramp-up with planned general availability in 2Q, 2010. " With the new version of SAP NetWeaver CE 7.2, you are able to design and develop your "own practices" as business rule-based, SOA-enabled, composite business processes & applications with the Eclipse-based SAP Developer Studio" - SAP AG There are Two 'versions' of Visual Composer (VC)

It is a browser- based modeling and design tool for rapid application development and prototyping in a code-free development environment SAP NetWeaver Visual Composer is a tool to visualize the data

Visual Composer is Easy for Power Users to Learn Visual Composer is a power user tool that is simple to learn for someone with a little bit of technical background (i.e., controllers, report writers, analysts) Source: SAP Take advantage of prebuilt analytic business packages No coding required to create great-looking, Web-based cockpits

It All Starts with a Query The BEx Query Designer The query is the core method for accessing BI data. You can use existing queries in your SAP NetWeaver Visual Composer models

SAP NetWeaver Visual Composer Data Methods Can integrate data from multiple data sources, including SAP and non-SAP systems, into one model Different options available for data access include: BI Extension Kit Remote Function Call (RFC) Web services BI Extension Kit allows access to the following DataSources SAP NetWeaver BI 2004 (SAP BW 3.5 Support Package 14) SAP NetWeaver BW 7.0 JDBC XMLA

Visual Composer Data Providers You can use BI queries and views as Data Providers for SAP NetWeaver Visual Composer models You also can use BI query functionalities for exceptions and variables along with SAP NetWeaver Visual Composer models SAP NetWeaver Visual Composer allows access to BI history, favorites, and roles

11 SAP NetWeaver Visual Composer 7.0 Portal Publishing SAP NetWeaver Visual Composer design-time deploys Visual Composer models directly as iviews to the Portal Content Catalog You can then use SAP NetWeaver Visual Composer iviews in portal pages, roles, etc.

12 SAP NetWeaver Visual Composer 7.0 Using BOBJ Xcelsius SAP NetWeaver Visual Composer 7.01 (or 7.02) SP5 or higher allows you to use existing Xcelsius UI controls and use them inside Visual Composer. You can also use any Flex component made by Adobe Flex Builder (Flex 2 SDK). You can download flash objects & 'how-to' on sdn.sap.com (by Sap's Amir Mimran)

13 Details about Visual Composer Cockpits Delivered as part of SAP NetWeaver Portal in SAP NetWeaver BW 7.0 Usage Type (SP8 and higher) Different options available for rendering SAP NetWeaver VC output Flash Web DynPro (HTML) Flash provides high-end visualization of SAP NetWeaver VC models You can pick your own rendering method in the menu: Tools Options

This is a great site for quickly getting started with SAP NetWeaver Visual Composer and for down loading a free demo-version There Are Many Resources at the SDN Community

Many of the beginner questions have already been answered in the expert forums on the SAP Community Network SAP NetWeaver Visual Composer And the SAP Community Network

You can also learn from others experiences by getting plugged-in to the community network blogs dedicated to SAP NetWeaver Visual Composer SAP NetWeaver Visual Composer SDN Community Blogs

You can download a trial version on the SAP Community Network Downloading and Getting Started The Trial Version However, to put it into production you must work with your SAP account executive for a license. It is normally not covered by a general SAP license.

Remember that this is a power user task, so providing the group with some formal training (4-6 hrs) would be beneficial. Also, teach them your naming conventions. The first task is to create an overall model to store all your pages and iviews The name cannot have blanks or special characters You can organize your model in standard folder structures Creating a Model

If you dont have Adobe SVG installed, you must go to their Web site and download it. It is a small file and it is free. The models are actually graphics rendered with Adobe SVG (vector graphics) The SAP NetWeaver Visual Composer Add-Ons

First you must make sure that your SAP NetWeaver VC environment is set up with connection back to your SAP environment(s). The Work Environment Getting Connected You can also work with your technical team to set up connections to other non-SAP environments.

This tool bar allows you to zoom, access layers, insert grid lines for layout, and move objects. We can add items and see then from the highest level, or you can drill down on each item and configure them individually Navigation is provided as a toolbar and you can also zoom in on each item The SAP NetWeaver Visual Composer Configure Toolbar

SAP NetWeaver Visual Composer has many tools that power users can play with The fastest way to proficiency is to try the many features Very few things can break, and the undo button is always available The magnifying glass is helpful when the model is very complex and zooming in and out is cumbersome. The Magnifying Glass

When you are developing very complex models, it is very helpful to add annotations (comments) to document your work. Consider proposing standards within your company (i.e., dates, initials, and what needs to be documented). The Annotation Tool

Very large SAP NetWeaver Visual Composer cockpits can be hard to read The Browse feature allows you to see the cockpit in a tree format that makes it easier to navigate Graphical model displays can get hard to read once very complex dashboards are created. Getting an Overview Over Complex Models

The best way to create cockpits is to prototype it first, then ask for feedback. Since this is a discovery-oriented process, it is not a best practice to use functional specifications to create Web cockpits. Rapid Application Development (RAD) is the preferred methodology. Plan on spending serious time with users working on layout and Web page organization P.S.! You can use the SAP delivered calendar for display, or for users to interact with your data set Development Methodology

SAP NetWeaver Visual Composer uses the standard GUI Modeling Language (GML). If you are familiar with this language, you can see the code page under the Source tab. The Back-End GML Code

You can look at existing queries developed by others. In this example we will create a Web Cockpit based on two SAP NetWeaver BI queries. More advanced developers can also call Business Application Programming Interfaces (BAPIs) that are delivered with SAP NetWeaver BI to build complex applications. Step 1 Find the Data You Want to Model

Step 2 Selecting the Queries and Defining a Starting Point 1.After the query is selected, the metadata is transferred to the model. 2.We select one query as the starting point and can require users to use a prompt (in this example we will leave this blank).

1.We add a table view and select the fields we want from the query. 2.We give the table view a meaningful business name. Step 3 Adding a Table View Based on Query Data

Step 4 Adding a Chart view based on Query data 1.We add a chart view based on the query data. 2. We decide to make it a column chart. 3. The fields that we want to graph are selected. 4. We add animation to the column chart.

1.We select the fields we want to graph as different data series (columns). 2.We give each column a meaningful business name (this is what the users will see). Step 5 Defining Graph and Assigning Meaningful Names

We can suppress the sum rows from the query, so that the graphs are more meaningful and the tables are less cluttered. Step 6 Suppressing Zero Values from the Query

1.When a user selects a row in the country table, we want to show all the customers in that country and their sales. 2.We link the output from the country table view to the customer query and map the country-key value between the two objects. Step 7 Adding Navigation: Linking Tables to Other Queries

1.We also want to give the users the option to click on a country in the graph and see all the customers sales. 2.Again, we link the output from the country graph to the customer query and map the country-key value between the objects. Step 8 Adding Navigation: Linking Graphs to Other Queries

Previously we added a table and a graph of country sales. Now we want to add similar views for customer sales. 1. First we add a table view. 2. We select the fields to be displayed from the query. 3. We give the table a meaningful name. Step 9 Adding a Table View for Customer Sales Data

Now we add a pie chart. 1. First we add a graph view. 2. We select the pie chart type and the fields to be graphed. 3. We give the field a meaningful business name. Step 9 Adding a Table View for Customer Sales Data (cont.)

Again, we suppress the sum rows from the query, so that the graphs are more meaningful and the tables are less cluttered. Step 10 Suppressing Zero Values from the Query

In the layout section we arrange the objects and resize them so that they look good. We also compile the model and can now view it in the Portal Step 11 Layout and Compiling of Dashboard

All country sales are displayed based on the first query The Result: The Web Cockpit in SAP NetWeaver Portal

By clicking on the country in either of the top views, the bottom views display sales for those customers The Result: Navigation Between the Graphs

43 DEMO A Cockpit in 8 minutes

External Web services such as email, stock quotes, news services, and weather maps can also be integrated into your SAP NetWeaver Visual Composer cockpit. External Web Services

Each Web service may require different input, so you have to spend some time trying out what works for your site and how to format it. External Data Providers Web Services

Performance Tips: BIA and Summary Cubes 1) If your cockpits are at a higher level such as weekly or monthly, consider the use of summary cubes to reduce the data accessed (also take a look at building aggregates). 2) For high volume or high number of users, you should seriously consider the BW Accelerator Solution. This compresses the data and stores the data in memory (no disk access when queries are run). This is hyper fast

48 Making Cockpits Fast Using the Cache as a Data Provider It is very beneficial to use the cache as the method for data service retrieval This makes the cockpits faster by relying on previously accessed data stored in-memory You can also use broadcasting to cache as a method to pre-populate the cache as well Since a cockpit may have many different DataSources (queries), it can take quite some time to execute them if the memory cache is not used consistently

Leverage the OLAP and the MDX cache to speed up the initial loading of the web page. Consider using jump-to and drill down links to more detailed information. Performance Tips: Using jump-to and drill down query links If you pre-run the underlying queries using BEx Broadcaster, and cache the results, you can make the VC cockpits open much faster. You can then also use Web Application Designer to provide links to the underlying queries for more detailed information. When user click the link, the query will not be run again (already in cache).

51 The Future of Visual Composer We are confident that with the provisions made for migration to VC 7.1 or 7.2 and the great feature set in EP-2 for VC 7.0, our existing customers running VC 7.0 will enjoy the best of both worlds: the option to upgrade to VC 7.2 or to stay with the latest release of VC 7.0." - Source: http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/15801 Source: SAP, 2009 SAP: "In light of the progress made relating to parity between VC 7.0 and VC CE, our investment in VC 7.0 will be limited to maintenance after EP2 is released.

52 Upgrade Options are Limited so pick the right version There are no automated upgrade paths from Netweaver VC 7.0 to Netweaver VC 7.1 or 7.2. Customers who want to use Netweaver VC 7.2 will have to keep both running and migrate the content from 7.0 to 7.2 manually. Plan carefully how you want to use Visual Composer and pick the version you want: 7.0 for SAP BI focus and 7.2 for BPM and composite applications.

In the Tools Options section, you can control items such as auto save, display levels, formats, highlights, and more. These preferences are stored for each user and can be personalized. SAP NetWeaver Visual Composer Options

55 Who gets to use the SAP Visual Composer? There is a temptation for the IT community of wanting to keep the Visual Composer tool under their domain That is a mistake - Spend time teaching Super Users VC.
