Once you have sent a BizTalk purchase document, you might want to check that the document was actually sent in the Outbound Purch. Document Hdr. table, which lists documents as sent or unsent.
To check whether a BizTalk purchase document was sent, follow this procedure:
Open the Sent BizTalk Purch. Document window.
Click Document, List to see a list of all sent BizTalk purchase documents.
Check if the document can be found here. You can identify the document by looking at the No. field. If the document is not here, it is still waiting to be sent and can be found in the Unsent BizTalk Purch. Document window.
