Difference between RSA5 and RSA6

What are all the differences between RSA5 and RSA6?

RSA5 - Contains all the Business content data source in Delivered version.

RSA6 - After activation from RSA5, the delivered objects will come to RSA6 as a Active Version.

T-code used in Extraction:

RS02 -> Generic Datasource

SE11 -> Database dictionary

SE37 -> Function module

LBWE -> Logistic Datasource

LBWG -> Deletion of setup table data

RSA5 --- Transfer business content data source

** Make available these data source to bw side for extracting data.

RSA6 --- Data source enhancement

** Enhancement of data source to include extra fields in it.. editing, displaying, test extraction of data source (rsa3) these are functions available in rsa6.

In transaction RSA5 you will get the DataSources in their Delivered State whereas in Transaction RSA6 (Post Process DataSources and Hierarchy) you can view the Activated DataSources in their activated state which is being done in RSA5 only.

Elaborating the main point.

RSA5 - Transaction from which business content data sources delivered by SAP can be activated/installed for productive use with live data.

RSA6 - Transaction to maintain the currently active data sources in your system.  Here you would find custom and SAP delivered installed datasources. You could branch to changing the data source from here.

Now, in RSA6 you can not only see SAP datasources currently active in the system, but also the custom datasources (Y* or Z*) the you have created and are activated in the system.

So, in a nutshell we can say that RSA5 gives all the DELIVERED datasources in the system and RSA6 gives all the ACTIVE datasources available for use.

RSA5 -> 

In the BW system, we call transaction RSA5 Install Data Sources from Business Content to install the DataSources from the application components.

We have to install business content using RSA5 before we can use it in SAP R/3.

By means of installing business content (BC) we are changing version of BC component from delivered "D" to active. No modifications to the datasource are possible here.  After installing only, we can use the datasources in LBWE.

RSA6 ->

Once you activate the datasource in RSA5, it will be available in RSA6.

Rsa6 list active datasources, as you can see in menu, functions : create application component, display/change datasource, test extraction (similar to rsa3), and enhance datasource.  Here user could modify the Data Sources. You can change the data source in RSA6 like you can append the fields you can hide the fields and make the fields selection enabled.

The function is same in r/3 and bw.
