SAP design has /101 will not reduce /582 as it is prior year OP and tax the whole gross. after calculating taxes, system is deducting /582 first from gross then trying to take taxes. In this case, as it is 100% recovery there will be no amount left after recovery to deduct taxes hence /NXX
Even though employee not getting any pay, he is supposed to pay taxes as it is current year earning.
/582 should be taken from net as it is nontaxable post tax deduction. SAP solution for /582 acting as pretax and creating /NXX.
SAP should fix this and provide an automated solution.
