We work SRM version 550 SP 14.
We implement the extended classic scenario the Backend system is ECC. We work without the SUS - supplier self service.
The scenario is
1.A purchase order is sent to a vendor XML Messages (in XML format from the Enterprise Buyer system to the supplier system).
2.The vendor accepts the purchase order (PurchaseOrderConfirmation) with XML Messages.
3.We use the ServiceAcknowledgementRequest to create confirmation in the EBP. sent from the vendor by XML.
The problem is that after the confirmation received from the vendor the document that create in the EBP Is not post to the backend and stay in the status Approved.
Can any one have the clue what is missing.
