A buyer can decide to close an active negotiation and restart it. There are several reasons why this might happen. If the negotiation is an RFQ, the initial round might have been simply for information gathering purposes, or the buyer may decide to change negotiation criteria such as terms and conditions, Quote/Bid controls, or the invitation lists. Once the buyer has published the updated RFQ/Auction, notifications are sent to the original and any newly added participants.
You respond to a second-round negotiation the same way as to the initial negotiation. After you have located the negotiation in which you wish to participate, you can respond with your new Quote/Bid. If the buyer has updated an item for the new round, you will need to respond to that item again. Your prior response price may have been carried over as the start price for the new line in the new round. If so, when you rebid on that line, you are required to submit a lower price than your bid in the previous round. If the item is unchanged from the previous round, your prior response is carried over to the new round.
Once you have displayed the new negotiation, you can easily identify the updated information by clicking View New Round Summary. The Multi-Round Modifications Summary page shows you negotiation information that has been updated since the previous round.
After you have analyzed the updated negotiation information, you can continue placing your response.
