Question:
 
A datasource was changed and a document date was added to the standard datasource. 
 
How to find which user has changed the datasource?
 
Answer:
 
You can use table ROOSOURCE and provide your data source here.
 
ROOSOURCE is a table in the source system which has information about all the data sources in the system.
 
When you create a datasource it will update to the three tables:
 
- ROOSOURCE
- ROOSFIELD
- ROOsourcet
 
Take OLTP version as A and then execute.
 
In the output you can see the last change user and its time stamp.
 
or
 
You can use the TCODE : RSA2 (Datasource Repository ) to display the datasource.
 
In the general Tab you can see the Last Changed by : and the date and time of change.
 
 
Error:
 
Error message: Datasource does not exists in version A.
 
It means the datasource is not active in the system, you will have to activate the datasource from RSA5 
 
Make sure you are providing the right technical name of the datasource while checking.
 
 
Notes:
 
You have to activate your Data source first and then check in the table ROOSOURCE with OLTP version as A and then execute.
