Dear Community,
I would like to request your help on clearing amount of “Unbilled Prepayment Total” field under “OTHER” tab of a purchase order. We created a PO with 2 detail lines with same price “14,673,000”.

After that we made one Prepayment Bill for first line of the PO.

And we paid through Check and Payment Screen.

After that, actual Bill came in and the amount was only “13,480,699”. So, we created Refund form for the remaining “1,192,301” and linked with Prepayment.

Now, back to the Order and we creat another Prepayment Bill for another line. But when we try to release it, it says “PO Error: The value of the Unbilled Prepayment Total box of the PO00001856 purchase order cannot exceed its unbilled or total amount.”

So, I check PO and it has “1,192,301” unbilled prepayment total amount. Now, I cannnot continue creating second Prepayment Bill for second line. Why not Refund amount of the first prepayment does not reconcile in here? Or am I doing incorrectly? Please help.

Thank you all in advance.
