We are currently exploring adding Request for Quotation to our processes. Our current process is that Purchase orders are released from Planned orders. We are looking at converting Planned orders to Request for quotations. Multiple parts will be on one solicitation to multiple vendors. An issues that I am trying to solve is if a part is not accepted as a winning bid, either intentionally or accidently, it is automatically rejected. What happens to rejected parts? I ran MRP and it does not appear to return to planned orders. I see that I can add another vendor, but I am not able to add a rejected vendor back to the quote. Is there a way to reverse the rejection in RFQ's?
