1. If the request has already been marked as "completed" then you'll need to mark it back as "Evaluating." Requests that just finished (proposal passed) remain in evaluating status until a user marks them as "Completed" so this step may not be necessary.
2. Navigate to the "Firms" page and click the "Manage Firm" button for the firm that you'd like to make a revision.
3. Click "Reopen Request" for the firm. This will only notify the selected firm that the request has been reopened to them.
If the "Reopen Request" button is greyed out that is because the request is already open because the proposal.
Auction Requests: the request remains open for all firms until the auction finishes. The initial due date in an auction request is a soft deadline and does not lock firms from submitting or revising proposals in the system.
Non-auction requests: Requests without an auction remain open until the proposal due date. After the due date the request locks for all firms.
If there is no "Manage Firm" button, that may be because a firm has already been selected.
