We are using BC14 on prem.
Our accounts payable team was processing a payment journal for a vendor where they encountered an error that a certain line on the journal could not be a negative amount. When I reviewed the line in question, it turned out to be a negative-amount adjusting entry with a blank Document Type on the vendor ledger. This amount and the other invoices on the vendor ledger were still netting to a positive amount to be paid to the vendor, but I'm curious to know why the payment journal would not accept the line as a negative amount.
There was another vendor also on the same payment journal with lines as negative amounts, but those were from Credit Memo vendor ledger entries, so it seems that the payment journal was only having issues when the document type was 'blank' and the amount was negative.
Is this normal, or a bug?
