This is helpful from the PO part of things, ME21N, where it is bringing in the last purchased price, but I am not seeing in that thread anything about assigning vendors in ME57. So right now, it would tell me to select which vendor I wanted, vendor A or vendor B, and if I selected vendor A then it wouldn't bring the price in when I created a PO.
Is there a way so that vendor A wouldn't even show up in ME57 unless it was valid?
