The Action button is disabled in the Assignment.
Reproducing the Issue
Go to the Resource Scheduler work center.
Go to the Assignments view.
Search for the Assignment XYZ1 (where XYZ1 is the assignment id) and open it .
You can see the Action button is not-editable.
There is no option/content under the action button, hence we have made it disable.Currently, you can only edit the Status and Assignment Note.
This is current system behavior.
