The invalidation of crew evaluation documentation is controlled by role permissions. Roles and users with "invalidation" permissions can invalidate crew assessment documentation.
The user log in to the OLISS Web side, click on the "Setting→ Role Authority" interface in order, and can find the target role by filtering conditions such as role name. Click "Edit" on the right side of the target role to enter the editing interface, find the Crew Management - Crew Evaluation in the menu permissions, check the "Invalid" permission, and then click "Confirm".
After the role permissions are checked, in the Crew Management - Crew Evaluation interface, for the documentation of "Approving/Approved", it can be operated as "Invalid".
