How to reverse Purchase Order prepayment invoice in AX 2012?

Dear Experts,

Could you please advise on how I can reverse a PO prepayment invoice?

I created a PO and posted a PO prepayment invoice of 100%. Just then I want to update tax for the PO as well as for that invoice but can’t find how to reverse it.

I tried to create a negative line but cannot since system does now allow a prepayment limit (100%) greater than PO balance (zero due to the net-off between negative line and original line).

I am using AX 2012 R3 CU8 and the PO is not yet receipt updated and not yet applied prepayment.

Any of your suggestion would be highly appreciated.

Thank you!

One way i see is to cancel the purchase order, that would reverse the vendor prepayment invoice.

Then update the purchase order again and apply the prepayment and invoice

Thank you very much for your nice advice, Kranthi.

I tested and found it was probably the best to reverse the invoice.

You can also verify the solution, if that was really helpful.

Hi Kranthi,

I checked the solution you suggested to cancel the PO and open the same PO, the prepayment transaction get reverse (Transaction entry ) if i will check the vendor transaction, but when i will check on the vendor prepayment invoice on the PO there is non extra line which show the reversal or even on the existing voucher there are no extra line which show the voucher is reversed.

Can you please put some light on my doubt. Thanks in advance.
