The SAP BI Core Toolset
SAP BI is an
enterprise-wide
comprehensive
decision support
(DSS) system for
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. VC is an extension of those tools.
4
Getting Started - In SAP-BI it all starts with a query
The 3.5x BEx
Query Designer
The new 7.0 Query
designer was totally
re-developed in MSVisual Basic .NET
The query is the core method
for accessing SAP BI data. You
can use existing queries in your
VC models.
The NWBI 7.0 BEx
Query Designer
What is Visual Composer
Visual Composer is a tool to visualize the data. It is a browser-based modeling
and design tool for rapid application development & prototyping in a code-free
development environment.
6
Visual Composer for Complex cockpits
Modeling of BI applications using the BI kit of the Visual
Composer allows business users to create analytical content
for SAP portal. It offers the integration with BI InfoProviders,
views, BEx web applications, PDF and more via WEB API as
access to
other data
sources such
as OLAP and
relational data
sources) via
Java
connectors

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).
No coding required to
create great-looking
Web-based cockpits
Take advantage of
prebuilt analytic
business packages
Source: SAP
Visual Composer and WAD
•
•
Visual Composer integrates with Web AD-based applications
using Portal Eventing Framework
For example, BW Web API can pass a filter value from a BEx Web
application to Visual Composer
 and vice versa
12
Web Application Designer for custom applications
WAD can also incorporate
other SAP VC web items
into powerful cockpits and
custom report centers.
While WAD can be used by developers
without extensive HTML and Java
scripting knowledge, these skills will be
useful on most projects.
Visual Composer 7.0 Portal Publishing
•
Visual Composer Design
time deploys Visual
Composer models
directly as iViews to
Portal Content Catalog
•
You can then use Visual
Composer iViews in
portal pages, roles, etc.

Modeling Overview
1.
In this section we will review some of the technical
options in SAP VC and take a look at the purpose of each
of these.
2.
After this, we will see a demo of how to build SAP VC
model from start to finish.
3.
We assume you have never seen the tool before and will
go through the demo and the overview step-by-step
19
Download and getting started – The trial version
You can
download a
trial version on
the SAP
Community
network.
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 BI license.
Creating a model
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
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 you naming conventions
The SAP VC add-ons
The models are actually graphics
rendered with Adobe SVG (vector graphics)
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 work environment – Getting Connected
First you must
make sure that your
Visual composer
environment is set
up with connection
back to your SAP
BI environment(s).
You can also work with your technical team to setup
connections to other non-SAP environments
The Portal Web Page container
You can create
individual iViews
that are shared in
other applications
such as WAD, KM
folders and web
pages.
You can use the
portal page to
group iViews.
Using the compose icon on the right, you
Can add iViews and Portal pages to your model
Alternatively, you
can make complex
iViews that have
many different
display levels
The SAP VC Configure Toolbar
We can add items
and see then from
the highest level,
or you can ‘drilldown’ on each
item and configure
them individually.
Navigation is
provided as a
toolbar and you
can also zoom in
on each item.
This tool bar allows you to zoom, access layers, insert
grid lines for layout and move objects
The magnifying glass
SAP VC 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 Annotation tool
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 iView in SAP VC
iViews can be graphical (charts) or tables and links between iViews and
queries can create complex dashboards with many navigation options
Getting an Overview over complex models
Very large 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
Development methodology
Plan on spending
serious time with
users working on
layout and web page
organization.
PS! you can use the
SAP delivered
calendar to display, or
for user to interact
with your data set.
The best way to create cockpits is to prototype it first, then ask for
feedback. Since this process is discovery oriented, It is not best
practices to use functional specifications to create web cockpits.
Rapid Application Development (RAD) is the preferred methodology
The Back-end GML code
SAP 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
Step 1 – Find the data you want to model
You can look at existing queries
developed by others.
In this example we will create a web
cockpit based on 2 SAP BI queries
More advanced developers can
also call Business Application
Programming Interfaces (BAPI)
that is delivered with SAP BI to
build complex applications
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)
Step 3 – Adding a table view based on Query data
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 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
Step 5 – Defining graph & assigning meaningful names
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 6 – Suppressing zero values from the query
We can suppress the sum rows from the query, so that the
graphs are more meaningful and the tables are less cluttered
Step 7 – Adding navigation: Linking tables to other queries
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 8 – Adding navigation: Linking graphs to other queries
1. We also want to give the users the option
on clicking on a country in the graph and
see the 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 9 – Adding a table view for customer sales data
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 pie chart 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 10 – Suppressing zero values from the query
Again, we suppress the sum rows from the query, so that the
graphs are more meaningful and the tables are less cluttered
Step 11 – Layout and Compiling of dashboard
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 SAP Portal
The Result: the web cockpit in the SAP Portal
All country sales are displayed based on the first query
The Result: Navigation between the graphs
By clicking on the country in
either of the top views, the
bottom views displays sales for
those customers

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, and you can
also use broadcasting to cache as a method to pre-populate
the cache as well.
51
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
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.
52
Building aggregates is easy – Propose from statistics
This example shows how to
build aggregates by using
system statistics to generate
proposals
Note: To make this work, the BW
statistics must be captured.
•
•
Select the run time of queries
to be analyzed (e.g., 20 sec)
Select time period to
be analyzed

Only those queries executed in
this time period will be reviewed
to create the proposal
53
Correct Aggregates Are Easy to Build – Propose from Query
We can also create proposals
from the Query user statistics.
To make this work, a
representative number of
queries must be executed to
gather the statistics to optimize
from.
We can also create proposals
for aggregates based on
individual queries that are
performing poorly.
54
Building aggregates fast for your SAP Visual Composer cockpit
The process of turning 'on' the
aggregates is simple

Speeding up the SAP VC Cockpit – Filling aggregates
Make Dashboards fast - Use the Right Read Mode for Queries
Select the right read mode. Three query read modes
in BW determine the amount of data to be fetched
from a database:
1.
Read all data (all data is read from a database and stored in
user memory space)
2.
Read data during navigation (data is read from a database
only on demand during navigation)
3.
Read data during navigation and when expanding the
hierarchy
Reading data during navigation minimizes the impact
on the application server resources because only
data that the user requires will be retrieved.
Source: Catherine Roze
57
Make Dashboards fast - Read mode for large hierarchies
For queries involving large hierarchies with many nodes, it would
be wise to select Read data during navigation and when
expanding the hierarchy option to avoid reading data for the
hierarchy nodes that are not expanded.
Reserve the Read all data mode for special queries—for instance,
when a majority of the users need a given query to slice and
dice against all dimensions, or when the data is needed for data
mining. This mode places heavy demand on database and
memory resources and might impact other SAP BW processes
and tasks.
A query read mode can be defined either on an individual query
basis or as a default for new queries using the query monitor
(transaction RSRT).
58
Make Dashboards fast - Condition & Exceptions
Minimize conditions-and-exceptions reporting. Conditions &
exceptions are usually processed by the SAP application
server. This generates additional data transfer between
database and application servers.
If conditions and exceptions have to be used, the amount of data to be
processed should be minimized with filters. When multiple drill-downs
are required, separate the drill-down steps by using free characteristics
rather than rows and columns.
This strategy results in a smaller initial result set, and therefore faster
query processing and data transport as compared to a query where all
characteristics are in rows.
This strategy does not reduce the query result set. It just separates
the drill-down steps. In addition to accelerating query processing, it
provides the user more manageable portions of data.

- a 39% decrease in
query execution time
60
Make Dashboards fast - RKF & Line Item Dimensions
1. When Restrictive Key Figures (RKF) are included in a query, conditioning is done for
each of them during query execution. This is very time consuming and a high number
of RKFs can seriously hurt query performance
Recommendation: Reduce RKFs in the query to as few as possible. Also, define
calculated & RKFs on the Infoprovider level instead of locally within the query. Why?:
 Good: Formulas within an Infoprovider are returned at runtime and held in cache.
 Bad: Local formulas and selections are calculated with each navigation step.
2. Line item dimensions are basically fields that are transaction oriented and therefore,
once flagged as a ‘line item dimension’, is actually stored in the fact table. This
results in faster query access (no table join).
Explore the use line item dimensions for fields
that are frequently conditioned in queries.
61
Make Dashboards fast - Reducing the Query processing time
Problem: Calculated Key Figures (CKF) are computed
during run-time, and a many CKFs can slow down the
query performance.
Solution: Many of the CKF can be done during data loads & physically
stored in the InfoProvider. This reduces the number of computations and
the query can use simple table reads instead. Do not use total rows when
not required (this require additional processing on the OLAP side).
Problem: Sorting the data in reports with large result sets can be time
consuming.
Solution: Reducing the number of sorts in the default view can improve
the report execution & provide the users with data faster.
PS! Reducing the text in query will also
speed up the processing some.

SAP VC Performance trick: Avoid Outdated Indexes & Database statistics
Database statistics are used by the optimizer to route queries. Outdated
statistics leads to performance degradation. Outdated indexes can lead
to very poor search performance in all queries where conditioning is
used (i.e. mandatory prompts).

For high volume Infocubes, or cubes that have a high number of users, the
percentage used to build the DB stats can be increased from the default 10%
to 20%. This may yield more accurate query routing and better query
performance (consider this especially for cubes with ‘old data’ partitioned)
You cannot drive a Ferrari on a “dirt-road “ – right data design
When you flag a dimension as “high cardinality” SAP
BI will use a b-tree index instead of a bit-map index.
This can be substantially slower if the high
cardinality does not exist in the data in general (starjoins cannot be used with b-trees).

Who gets to use the SAP Visual Composer?
There is often a temptation for the IT community of
wanting to keep the Visual Composer tool under their
domain – That is a mistake
The IT community should actively work with the power
and casual users to improve human capabilities and
thereby teach them to become more productive
employees.

Chinese Proverb
7 Key Points to Take Home
•
SAP Visual Composer is a tool that is easy to learn
•
The tool is intended for PowerUsers – not primarily IT
•
SAP 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 BI Accelerator if you have many users of the VC
models
•
Seek advise of best practices and plan on integrating data across
systems, web services and other non-SAP sources.
