Lockbox is currently configured for partial payments. The partial payment checkbox is ticked in OBAY. However, the problem is that when the customer is making a short payment on an invoice, Example $500 invoice. In record 4 invoice number 90123456 payment amount $500. They are then sending another record 4 with same invoice number 90123456 with a payment amount of -$100. This is causing the original invoice to be cleared and leaving an outstanding balance of 100.00 on the customer account. The business would like to keep the original invoice open. Kindly offer any suggestions
Example:
6001001000058710001112223330054320000077777
400100111 090123456 00000500000000000000GH
400100121 090123456 -0000100000000000000GH
Thanks.
