When working on a quote in the Supplier Portal, you may eventually get that quote returned by the buyer with several items rejected. If you make a few quick price changes on the rejected line items in your original Excel Workbook from the first quote and attempt to re-submit the same file you will get an upload failure.
When Request for Quote (RFQ) pricing is rejected in our system from the buyer, you must download a new Excel Workbook from that RFQ. Then, update the pricing but do not change the status column, use the Excel as is. The system will modify that status to "requoted" automatically when you upload.
Resubmitting your quote in response to a previous rejection should yield success. If instead, after upload, you see errors noted, scroll across your working area input table and find any cells highlighted with red boxes - this indicates an error, and if you correct it, you should be permitted to proceed.
