I need to void a vendor prepayment (posted in a closed period) that is fully applied (bill and payment application posted in a closed period). The void button is not showing, I presume because it is fully applied. The prepayment was never actually made in the bank. Any ideas on how to reverse this transaction in the current month? I think a JE might be the only way.

the button is not showing because the process is completed as far as NS is concerned. with your periods closed it does seem JE is the only answer.

Thank you that is what I thought
