Hi SCN,
I have the user with following privileges:
SYSTEM Privileges: CATALOG READ,CREATE STRUCTURED PRIVILEGE,DATA ADMIN,STRUCTUREDPRIVILEGE ADMIN,USER ADMIN
PACKAGE Privileges: SECURITY
OBJECT Privileges: _SYS_BI,_SYS_BIC and REPOSITORY_TEST
Am able to create a AP, but not able to assign to a user. Checked different threads and documents, Am able to add with "SYSTEM" user but not with the generic user i have 
I can't do tracing as it is disabled in the client system
Am i missing something here? Can someone help me please?
Regards,
Krishna Tangudu
