In release 4.5A, you can now calculate deductions with the 'Balance and Totals' function. This allows you to deduct a set value each month from an employee's pay. The system will calculate any remaining balance and deduct the amount in the last month of the deduction cycle.
Information for 'Balance and Totals' are stored on infotypes Recurring
Payments/Deductions (I0014) and Additional Payments (I0015). For additional information see
Wage types for Balances and Totals.
