Calculating for hourly pay types and the correct Time and Attendance Batch is not selected. When calculating deductions based off of gross pay, there must be a corresponding pay type in order for the deduction to calculate successfully.
A calculation only includes benefits and no other pay types.
If calculating for hourly pay types with incorrect Time and Attendance batch:
Recalculate payroll selecting the correct Time and Attendance batch
If calculating for a benefit with a fixed amount and no regular pay:
Delete original calculation and recalculate with additional benefits.
Expire benefit, create a one-time pay type in place of benefit and recalculate payroll.
