Background job fails for BDC profile creation and role assignment

Hi Experts,

I have created a BDC Function module for Tcode 'PFCG' for profile creation and role assignment, and called this FM in my zprogram. the problem is that when i run this program in foreground it executes succesfully, but if i schedule it in background it fails throwing error in job log 'Role 'Z...' does not contain any active authorizations'. But i have created one more program to create authorization objects which runs before this zprogram.I have also checked the authorization object in 'RSECADMIN', it reflects active. I dont understand whats happening exactly when it runs background.

Below is the process of job

   1. ZMIS_AUTH_OBJECT_CREATE

       Variant : auth-create

   2. ZMIS_AUTH_ASSIGN_TO_ROLE

       Variant : auth-assign

The problem is in second program, runs in foreground but fails in background.

Code which i have written in my second program
