Hi Mrinal
Please debug and check what kind of exception is returned after your CALL statement.
NO_SHOW_AUTH = 7 " No Display Authorization
NO_UPD_AUTH = 9 " No Maintenance or Display Authorization
ONLY_SHOW_ALLOWED = 10 " Display but Not Maintenance Authorization
MAINTENANCE_PROHIBITED = 14
Accordingly, you may have to review it with your basis consultatnt to provide appropriate for this function module.
Regards,
Venkat
