When you try to delete a Job Calculation, the system may show an 'in use' error even if the calculation has never been applied to a payroll run. This happens because the system validates deletion eligibility by comparing the calculation's effective date against job history and payroll history dates — not by checking whether the specific calculation was used.

The system checks whether any payroll history has been posted in a period whose effective date falls within the date range of the Job Calculation. If it finds a match, it treats the calculation as in use and prevents deletion — regardless of whether the specific Job Calculation record was referenced in that payroll run.

This means a Job Calculation entered with the wrong date may still show as in use if other payroll history exists within the same date range.

If you cannot delete the Job Calculation, use one of the following options.

Marking the Job Calculation as dormant removes it from active use without deleting it. The record is retained in the system but will not be applied to future payroll runs.

If a correct Job Calculation already exists with a later effective date, you can leave the incorrect record as non-dormant and update its amounts to match the correct values. The later-dated calculation will take precedence for future payroll runs.
