I an surprised this is not already out there.... i did search extensively and did not find it. I have an issue where I have an OPEN payment that is partially applied and I need to unapply it. The payment is not a check. I is a manual payment that was applied to the wrong invoice. I can not unapply. I can not void the payment. I am told I need to create a dummy invoice, apply it to the payment so the payment can be voided and then void the dummy invoice and then reenter the payment. This is bizarre. Please vote for this...... We need this fixed. IF a payment is open we should be able to unapply.
