Requirement-PCR

Hello Gurus

Please suggest me how to go for a PCR for below scenarios

Requirment1

If wt 5000 is available in RT and check the amount, if amount is more than Zero means then for that payroll cycle add the amount of WT 5000 to technical wage type /101

Requirment2

Have WT 0001 and 002 in RT

  WT 0001 * 4  (WT 0001 multiply by 4) = Value/Amount

value/Amount * 0.9 (value/Amount multiplied by 0.9)

this amount – WT0002 amount
