We have a very special situation here, we receive spot buys from our customer, and we HAVE TO (and need to) produce and send material without having a Blanket PO, but we already submitted a PPAP for every part number. Now, we need to get the material from OUR suppliers PPAP'ed, but, because there is no blanket PO, they say they won't submit any PPAP for spot buys, that they need a blanket PO to begin PPAP process. Is there any way to make the suppliers to submit us the PPAP of there is any clause we can use to make exceptions? material not approved thru PPAP process?
