It seems that logical system name for BW system moved to QA from DEV with customizing transport.
The problem is that in the customizing change that was moved from P1L ( DEV ECC ) to P1R ( QA ECC) , source system was not changed accordingly and it is now wrong in P1R. P4L ( DEV) and P4R ( QA) are the BW systems
The settings in P1L – the source BW system is P4LCLNT100:
The same settings in P1R (after transport) – the source system is still P4LCLNT100 though it has to be P4RCLNT100:
Now how do I change the logical system entry in table TBPBWRET00 in QA system
