BW Training 2 - Basics of Net weaver & SAP Workbench

SAP NETWEAVER :

Netweaver is a combination of various applications. This is developed based on concept called Enterprise Service Architecture [ESA] (earlier SOA).An application which provides end 2 end solution of business is called as ESA application . Its is a combination of PI, BI & EP together called as NETWEAVER suite.

APPLICATION PLATFORM:

As we got data from various applications, it will have different business processes and different formats (XML,IDOC,) all these will be in application layer

PROCESS INTEGRATION LAYER

Imagine You need to integrate data from web based and SAP , We can't combine /convert XML and IDOC .As data is from different formats /business process ,We need to integrate all the in process integration layer . In one world PI brings data from any where and any format and sends data to any where and any format . In the above example as we are sending data from web to sap , so we are converting XML to IDOC.

INFORMATION INTEGRATION LAYER (BI in old versions )(BW from latest versions)

This is what your BW layer . All our data stores in BW Layer .Suppose imagine if we are processing data from sap R/3 , no need to load to PI , We can directly load in BW.

In BW layer , we will be doing Modelling ,extraction and generating reports

PEOPLE INTEGRATION LAYER (Enterprise Portal)[EP]

This is one of the building blocks in the SAP NetWeaver architecture. With a Web Browser, users can begin work once they have been authenticated in the portal which offers a single point of access to information, enterprise applications, and services both inside and outside an organization. The portal provides access to business processes and information, social collaboration and content management across various consumption channels.

Terminology of basic SAP Screen

Data Warehousing WorkBench (DWWB)

This application we are going to in BW .This can be triggered by using transaction “RSA1”.

It has got 2 frames, one is left frame and right frame.

Left frame has got various tabs.each tab has different levels

In the right frame , it will display all objects according to what we select in left frame

Functions of DWWB :

1. Modelling-

whenever we want to create any object in BW, we use Modelling tab .

2. Administration -

To schedule load in the background and to monitor them

4. Transport connection

To transport objects from one system to another , All objects are created in development system will be unit testing whether the new objects working fine or not and moving these new objects to User Acceptance Test(UAT) and finally to live systems / production systems.

4. Documents-

To do the documentation .

5. BI Content

The readymade objects given in BI are called as BI Content objects .When ever you want to use these objects , we can go to BI Content tab . All Bi Content objects start with Zero.

6. Translation -

To translate the object from one language to another . Every object has got 2 names , technical name and description . Technical name cannot be changed .

7. MetaData Repository

Data about data is called Meta data . We can get information about all objects .
