ERROR on ME22n

Hello All

The Security team has created a test user in Q system , when this user is trying to execute the transaction ME22n , it is showing an error ' FUNCTION MODULE INTERFACE NOT VALID FOR INCLUDING LINKS ' (message class TD no. 768 ) as this is a business test user, it does not has authorizations for SE38 and debugging thus I cannot debug it in runtime . When I login using my (developer) id , the tcode is running fine . Could anybody help if faced this error before or could help me with the debugging with the test user.

Thanks in advance .
