What diagnostics show
For each uncovered shift, diagnostics show required and filled positions, location shortages and why candidate employees could not be used.
Common causes
- The employee is on leave.
- The assignment would overlap another shift.
- The employee reached a weekly-hours limit.
- A work-pattern or shift-transition rule excludes the date.
- Required rest would be violated.
- The employee cannot satisfy the required location.
- There are not enough active employees for the requested headcount.
Resolve a shortage
Correct the underlying data, reduce or move demand, or assign an employee manually when you have reviewed the warning. Rerun Auto-Assign for the affected range and compare the new diagnostics.
