Change the UME source system for AS Java ?

[symon_braunbaer]

Hello,

sorry, but a quick google search didn't return any reasonable results, so I decided to quickly ask...

We have a Java system, which has its UME user store in an ABAP system.
Now our functional guys have asked us to disconnect the Java system and connect it to another

ABAP system, meaning it will use the user store of another ABAP system, usage type ERP.
Is that even possible ? If yes, kindly guide me how exactly to do that...

Thanks a lot !!

Hi Seymon,

There is one problem you should consider:
All JAVA-Groups are stored as ABAP-Roles in the ABAP-stack. If you change the UME-connection to another  ABAP-stack you can loose  JAVA-groups. Without certain JAVA-groups the JAVA is not operational anymore.  Tarpan is right. You get an unsupported system.

Best regards

This is not gonna be a problem, because both ABAP systems are derived by a refresh from the same production system.
