Explanation
How can I change the due dates, notifications, and other contract deliverable details?
You can change the due dates, notifications, and other contract deliverable definition details in the Deliverables tab of a contract that is in Draft or Under Amendment status. Once the contract becomes active and deliverables are automatically activated creating deliverable instances, you can only make changes to deliverables status, notes and attachments using the Manage Deliverables task. For internal deliverables with a fixed due date that you can manually activate at any time irrespective of contract status, you can only make changes to deliverable definition details before you activate them.
