Yesterday, March 7, I disabled Purchase Tolerances so any change could be made to a PO and not have it go through the approval process again. I also The PO we're trying to make a change to was created before March 7 and we are trying to invoice this PO and add freight to it. I am getting a message the PO has to be re-approved when we add a line for freight. Is it because this PO was created before March 7?
