Edits cannot be made in the following cases:

The supplier of the purchase order cannot be changed if any rows on the purchase order are referenced on inventory receipts.

A row on the purchase order cannot be changed if that row has a completed status.

Tip                  To view the history of changes to a purchase order, click History. The Purchase Order History window opens. The Created By box displays when and who added the purchase order to the database. The Updated By box displays when and who updated the purchase order last.
