PO Net Price change after Invoice in Service PO

Hi,

We have created Service PO with item Category "D" and created only Invoice for that Service PO, Not doing any Service entry sheet for that Service PO.

Requirement is that Business want to Short close the service PO, We don't have any "delivery complete ind" in service PO.

Planed to check Invoice value and change the PO Net Price value, We planned to check  Header status of PO in that we will get Ordered value and Invoice Value or else EKBE table

If Validity end date reached the current ( system date) then we wil check EKBE table DMBTR field and check is it match EKPO_NETWR , is not we will update Net price with Invoice value in Purchase order.

We have Version Management Active in Purchase order.

Ex:  Service PO created for Value 1234 USD   and till now we have Done Invoice for 1000USD...  Now Validity end date reached today's date then we will make PO value to 1000USD, then it means PO closed .

Thanks and Regards
