Hello
Do you prorate the amount for mid year hire?
Do you allow outstanding amount to be carried forward for deduction in next year?
These are some of the questions unclear so far.
Now technically Function P0014 will your Wagetype and pass the number indicator and post which you will need to write a PCR and based on your schema place it in a correct place.
You will call this PCR just to process your WT for payment. You will need another PCR before this to move thw WT 1059 in to variable to be used in month of termination
Skeleton structure to get you started you might need to do a thorough testing. Here XX is date type from IT 0041 which will hold the date of hiring/entry
Regards
Ajay
