PSA Error: "Timecard Header may not be inserted or changed if its Assignment is Closed for Time Entry"
An error can occur when attempting to modify a timecard if its associated assignment is closed for time entry. To resolve this, the "Closed for Time Entry" setting on the assignment must be unchecked. This will allow for the approval or deletion of the timecard. The setting can be re-enabled afterward if no further time logging is required for that assignment.
