There are some good reasons to regularly run the Remove Completed Purchase Orders routine. This process can be included as part of your month end routine.
In Dynamics GP, removing completed purchase orders doesn't mean getting rid of purchase orders. So what does it do, and when should GP users be making use of it?
Remove Completed Purchase Orders is a routine for cleaning up closed and cancelled purchase orders. These are PO's that should initiate no further transactions. In the case that purchase history is not being kept, when a PO is removed it will be deleted from your records. So in this scenario the routine lives up to its name. Running the Remove Completed Purchase Orders routine will result in closed and cancelled PO's being moved to history. They are removed from the open table but are not deleted.
Once in history the completed PO's can no longer be re-opened with a change order status through the Edit PO window. Purchase Order Processing can be done more effectively since open and historical purchase orders can be viewed separately or together.
