• SAP NetWeaver Visual Composer is a tool to visualize the data• It is a browser-based modeling and design tool for rapid application

development and prototyping in a code-free development environment

What Is SAP NetWeaver Visual Composer?

Visual Composer is Easy for Power Users to LearnVisual 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)

Take advantage of prebuilt analytic business packages

No coding required to create great-looking, Web-based cockpits

Getting Started- In SAP NetWeaver BI It All Starts with a Query

The 3.5x BEx Query Designer

The NWBI 7.0 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

The new 7.0 Query Designer was totally redeveloped in Microsoft’s Visual Basic .NET

• 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

12

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.

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 for SAP NetWeaver Visual Composer — 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

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.

You can download a trial version on the SAP Community Network

Downloading and Getting Started — The Trial Version

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 don’t 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 Visual Composer environment is set up with connection back to your SAP environment(s).

You can also work with your technical team to set up connections to other non-SAP environments.

The Work Environment — Getting Connected

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 featuresVery 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

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).

Step 2 — Selecting the Queries and Defining a Starting Point

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 customer’s 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 SAP NetWeaver 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

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).

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”…

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

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

49

Speeding up Queries by Using Aggregates

• Aggregates are much less used by the SAP installation base than training and common sense should dictate.

• The interface to build the summary tables (aggregates) are intuitive and easy to master, but few are taking real advantage of them.

• Even among those that are using aggregates, many have poorly defined solutions & seldom monitor the usage, thereby limiting the benefits of this simple technology.

To avoid poor definition and usage, aggregates should be developed after the system has been in production for a while and real user statistics are captured.

The Future of Visual Composer

SAP NetWeaver Composition Environment, including SAP NetWeaver Visual Composer, continues to be the go-to product for creating composite applications

Source: SAP, 2008

Other Dashboard Options — SAP BusinessObjects Capabilities

• Dashboards can be built using Xcelsius® software

• Xcelsius+ will be launched later this year, and will be “the flagship product for data visualization & dashboards” (source: SAP AG, 2009)

• BEx Web Application Designer will not be enhanced further beyond SAP NetWeaver version 7.1

Who Gets to Use SAP NetWeaver Visual Composer

• There is often a temptation for the IT community of wanting to keep the SAP NetWeaver Visual Composer tool under their domain – That is a mistake

• The IT community should actively work with the power users and casual users to improve human capabilities and thereby teach them to become more productive employees

7 Key Points to Take Home

• SAP NetWeaver Visual Composer is a tool that is easy to learn• The tool is intended for power users – Not primarily IT• SAP NetWeaver Visual Composer is not going away • You should provide individual training to each of the power users• Spend serious time performance tuning the back-end queries and

data stores• Plan for SAP NetWeaver BW Accelerator if you have many users

of the SAP NetWeaver Visual Composer models• Seek advise of best practices and plan on integrating data across

systems, Web services, and other non-SAP sources
