Regarding AR transaction from AGIS source

Hi,

Whenever a transaction from AGIS source flow into AR, AR invoice was generated with one singe line.

When we see the transaction in AGIS, the transaction have multiple number of lines in AGIS. If the same AGIS transaction flow into AP side, it also having multiple lines (AP) same as AGIS transaction. But the problem is whenever it flow into AR the transaction contain one single line for the whole amount. I could see the transaction was created by Autoinvoice Master Program. The executable method is Spawned. So i am not sure how to check the program code.

This the standard logic to generate an AR transaction with single line from the AGIS source? Can you please advise on this query.
