SAP Note 28730 - Court Orders during Retroaction

Symptom:

The requirement is that if a Backdated change is put into a wage type
that affects arrestable pay, the positive or negative amount should be rolled forward to the current open payroll period and be included in arrestable pay for that period. That way any arrears can be recovered, and for the salary band types the employee pays the extra in the period
that they receive the extra money, or conversely they pay less in the period that total pay is reduced. Like all deductions court orders should never be recalculated retro-actively.

Cause and prerequisites
Solution
Due to the differences in useage between '/105', working net pay and arrestable earnings when in a retroactive situation, a new cumulation wage type for Arrestable earnings; '/141'.
As well as this new wage type we require two new retroactive wagetypes for the correct processing of court orders via backdated changes to the arrestable earnings amount.
Please note that due to the use of the new /141 arrestable earnings wagetype, all user wagetypes that should be deemed as building up to gross, should also be marked with an 'x' on position 41 of the cumulation calsses within T512W. That way /141 can be built up correctly.
