how to capture the value ?

Hello Everyone,

I am running a BDC program using call transaction , and I am updating some records in FB01 , then for each record a number is generated called document number ( bkpf - belnr ),

I want to capture the number generated for each record i process ?

if i process 10 different records at a time, then how to find which document number is generated for which record ?

will be rewarded ??
