Payment order field update

Hi All,

We are looking custom solution on payment confirmation post a payment order, we are able to create a payment order using function module “FKK_PAYMENT_ORDER_INSERT” and could not able to updating the payment field “XPYOR” (Item Included in a Payment Order), due to this we could not able changing the payment order status.

Can you someone suggest to update this field by BAPI or FM.

Regards,

Hari.
