GRC CUP 5.3 - user from mulitple system or multiple client
We are implementing GRC AC CUP 5.3 for a client and we are on SP 15 .
This client is having multiple countries hosted on multiple sap client of a system and not using any CUA ,IDM ,LDAP as common UME .
Now the requirement is during user creation/change request end user should be able to access user\roles from any client .
We set up User data source as one client but still not able to fulfill requirement .
Can you please share your experience on this ?
Thanks & Regards
