Finalizing a requirement freezes it forever and it can no longer be edited as is. To edit it, a new version of the requirement must be derived.
To derive a new requirement, click the button on the Versions tab of the requirement and click Yes to confirm. Only the latest version marked as Final is the only version for which a new version can be derived.
Note when a new version of a requirement is derived, linked test cases of the previous version do not carry on to the new requirement version. Test cases will need to be added to the newly derived requirement version, if needed.
Users will need to have project permissions to view and edit the requirement to perform this action. Depending on the settings of the user's project permissions, they may be able to view all the project requirements or just a subset of them. Users added to a specific requirement as a contributor, reviewer or co-owner will be able to view it.
