When responding to an RFQ, there is a "flags" section, which allows you to indicate specific statuses or aspects for the part you're quoting.
You can choose to flag an item as: No Bid, RoHS compliant, Lead Free, NC/NR (Non-cancellable/Non-returnable), Obsolete, or Tariff as applicable.
When uploading your quote responses, you can mark a flag by putting "Yes", "Y" or "1" in the corresponding cell. If a flag is not applicable for the line item, then leave the cell blank. Entering anything else besides these acceptable responses will create an error for the line item.
