Hi Thomas,
My achieve is: want to have a same type of internal table with FM '/NSL/ABP_SVC_POLICY_RETRIEVE'.
In order to debug and check the issue, so I put the same code in this system. Actually I will call this FM in other system by RFC, you know, in other system, don't have /PM0/ABWACOV or /PM0/ABWACOV_T, so I have to create it dynamically.
