Garnishments in a correction run

Hello -

We have a creditor garnishment that is not being processed during a payroll correction run. I noticed in some old SAP documentation that garnishments are not recalculated during a retro run. Assuming this is still true and that a correction run is viewed as a retro process then would this explain why our garnishment is not being calculated? Is there any way to get around that so that the garnishment is calculated and deducted during a correction run?

Thanks!!
