What are some repercussions of locking the date on a PO? We use them for approval for services and buying of office materials. We are not an inventory based company. There was a suggestion from the accounting team and procurement team to lock the PO date as the date it is being created. Right now they have some people back dating POs and it is messing with their reporting. I suggested to just used the date created field for reporting, but there was some push back.
