Hi all expert,

     Problem Description: If possible the system don't generate the intercompany AP/AR invoice for cross OU internal order process. Does oracle R12 support this business

We need the process like following. Can you help to check if Oracle R12 support the process like this?
1.Create internal requisition in A OU
2.Run create intenral order in A OU
3. Importe sales order in B OU
4. Picking and shipping in B OU
5. Receiving in A OU
6. End of process, there is no intercompany AR/AP invoice generation. 

 A and B belong to one legal entity,we use internal order process to transfer the good from A to B,For this process we don't need the intercompany AR invoice and intercompany AP invoice. we have another OU called C,for
