I am working on integrating ECC and SPP via CIF. When a Purchase Req or Purchase Order is created in SPP, it is transferred via CIF to ECC, then when ECC generates an order number, this is supposed to be transferred back to SPP to update the order number in SPP. This return update is not working. I am only catching the update in the CIF Comparison transaction (/SAPAPO/CCR). I get a CIF191 error, then I need to manually push the update to APO. Does anyone know if there could be a configuration I am missing, or any advice they can provide? It is hard to believe that you would need to run this manual process to update SPP. It also happens when I modify the PO quantity in ECC. This fails with error CIF188 and I manually push the update to APO again.
