We're having a situation where a lockbox file referencing the MICR number of customer A clearing an invoice in Customer B. Does anyone know why this happens?
The lockbox references MICR number of customer A but in the line item details it references an invoice of customer B. Ideally the program should first uniquely identify customer A with the MICR number and then, look for invoices within Customer A. It correctly cleared few invoices from Customer A, however, when it found the invoice that belonged to customer B, it went ahead and cleared that as well. This should not be happening unless the Lockbox sequence is to first identify the invoice with invoice number and then find the customer. I don't believe this is the standard functionality. Can anyone please help understanding this situation?
Additional info: I checked that MICR number was only maintained for Customer A, and also verified that Customer A is not set as an alternate payer to customer B. Thanks for your help!
