When a purchase order is created, then a change has to be made to the po, there should be a revision number added to or included on the purchase order. This was suggested to us by a quality auditor.
It would be nice to be able to view what the different revisions looked like as well. Maybe a right click functionality for the revision field to show the changes made along with the revision that made the change. If you were on Revision C you could see what changed from B to C as well as all the changes since the original.
What you are all describing is the revision for each individual line item (which I think should be an option on the main page not on the details tab).. but the PO itself should have a revision box. Preferably not a user defined field because that can easily be missed at the bottom of the page. There are many times where we need to update a PO after it has been processed
This feature is already available for a PO Line, i think it is at the bottom of the PO by Line, Revision Field next to Vendor REference....
This already exists, in the po line item under details there is a revision box. If you add something there the po will say "Revised" and that line number will be revised
You won't be notified about changes to this idea.
