BidTables cannot be removed from the Criteria section. BidTables are automatically assigned to the Criteria section so that the system can automatically combine all vendor responses into the Order List view. The Order List view remains as part of the project by default, in case Reviewers wish to compare prices between vendors.
If for any reason your Reviewers do not wish to make comparisons and selections in the Order List, they can simply leave it as is. Although their evaluation progress bar will not show as 100%, Vendors' scores will not be affected as there are no points associated with the BidTables, and you will be able to mark the project as Completed or award a Vendor if needed.
