Zero Payment is 'reconciled but unaccounted'

Hello,

the subledger accounting report returned by Create Accounting in AP is showing errors for a payment with a zero amount.

Initially there were two invoices, both were credited. this proved to be a mistake so a fake invoice was created that debited the returned amount, resulting in a payment with EUR 0 on it.

Somehow this payment is not accounted, where all invoices are fully accounted.

Where should we start when trying to resolve this issue?

We are on R12.1.2.

i attached the report, I replaced the bank account info with 'xxx'

kind regards,

Wilro
