Purchase Order Page Personalization's in Notes and Attachments tab

Summary:

We have Renamed a Attribute (Note to Receiver) to Justification and made the required field in the Purchase order - Notes and Attachments tab. And we are also having the Acknowledgement within days as required as it is defaulting from the Supplier Site config.

But when the buyer is creating a Purchase Order if he is not clicking on the Notes and Attachments tab he can submit the PO without filling in the Justification. The system does not throw any errors and allows the buyer to submit the PO for approval.

The Expectation here is to not allow the buyer to Submit the Purchase Order for approval without filling out the Justification in the Notes and Attachments tab.
