Enhanced Customer PO Number Validation

A new feature that was added with product update 4.40.0.1 is Enhanced Customer PO Number Validation. In Sales Order Options, you can now optionally choose to check for duplicate customer PO numbers in Sales Order Entry, Sales Order Invoice Data Entry, Sales Order History, Accounts Receivable Invoice Data Entry, and Accounts Receivable Invoice History.

In this video from Sage University we can see how to use the new feature.
