PO Revision Levels tracks a Revision Level for each PO Line, and automatically adds that information to the Purchase Order so it can be sent to your Vendor. The PO Rev Level is visible on all Purchase Order and Receiving windows and reports.
PO Revision Levels maintains a change history of Item Engineering Rev Level, and a history of Rev Levels assigned to each PO Line.
You can select a prior rev from Rev History when creating a PO it a part needs to be re-ordered at an earlier rev.
Since the Rev Level is attached to each PO Line, a reprinted Purchase Order will show the historically correct Rev Level, rather than the current Item Engineering Rev.
