Thank you for your response Alex.You are right,the user is getting it from another role which has authorizations like this.
Role 1 : Z:_MM02
Auth Object : M_MATE_STA
ACTVT 02
STATM V
Role 2 : Z:_MM_Processing
Auth Object : M_MATE_STA
ACTVT 02
STATM *
So now suppose in Role 2 if I change ACTVT to 03 then the problem would be fixed (I tried that already) but my question, is there any other way to do it without changing the ACTVT to 03 for Role 2 ? We need to have ACTVT 02 for Role 2. So what can I do about it?
