Payment Order Lot

Hi,

I am looking for a solution approach on bellow scenario for payment orders.

1. Customer will made a payment on portal, data will be validate by bank for real time check, and on successful scenario system should create a payment order lot and clear the outstanding debt.
2. On next 2 days will get the real time payment via file, and will post using payment lots to customer account.

Primarily to test this scenario, I am directly creating FP45 payment order lot but system is not allowing to post direct manual pay order lot to BP.

I am aware that Pay order is flexible solution for payment program, to test this manual payment I have done the following config checks.

For FPY1, payment method is marked as “Pay order”, does this cause any issue.

Kindly provide your clarification.

Regards,

Hari
