The Inbound Purch. Document Header Table
This field contains the date on which the pending BizTalk purchase document was processed.
If your program is set up to process automatically, any difference between the values in the Date Received and the Date Processed fields is due to a delay in program transactions. If, on the other hand, your program is set up to prompt you to accept the purchase document when processing, any difference is due to a delay in your acceptance of the document.
