Create reduction factors

This step enables you to define reduction formulas for wage types that are entered via infotypes 0008 Basic Pay or 0014 Recurring Payments/Deductions.

Since wage types from infotype 0008 Basic Pay are created for each partial period if changes in infotypes 0001 Organizational Assignment or 0008 Basic Pay are not made at the start of a period, these wage types must be reduced by factors which are created on the basis of the partial periods.

Wage types from infotype 0014 Recurring Payments/Deductions, on the other hand, are created just once per period. For this reason, reduction factors can only be used for these wage types that are created on the basis of the entire period.

Standard settings

The standard SAP R/3 system contains the following formula for reducing basic pay wage types for partial periods:

Planned working time (partial period) - unpaid absence (partial period)
divided by
Monthly working time according to the personal work schedule
The standard system contains two formulas for reducing wage types entered using infotype 0014 Recurring Payments/Deductions.
Planned working time (entire period) - unpaid absence (entire period)
divided by
Monthly working time according to the personal work schedule
Factor = 1 (thus no reduction) if at least one paid hour exists in the payroll accounting period

Actions

1. Check which reduction formulas you need
2. Make a copy of standard calculation rule XPPF and rename it ZPPF
3. Make a copy of standard calculation rule XPP0 and rename it ZPP0
4. Make a copy of standard calculation rule XPP1 and rename it ZPP1
5. Change the reduction formulas in personnel calculation rule ZPP1 to meet your requirements
6. Change personnel calculation rule ZPPF so that it accesses ZPP0 instead of XPP0
7. Change personnel calculation rule ZPP0 so that it accesses ZPP1 instead of ZPP0
8. Change personnel calculation schema XAL0 so that it accesses ZPPF instead of XPPF
