I have a lockbox setup using a csv file that has multiple lines per customer. I am looking at the file in notepad and all looks well when it comes to the header and detail lines. I have the setting for Lockbox Format Type set to Multiple Line, Lockbox Apply Method set to Specific Invoices and the header and row indicators set correctly. However, when I read in the file each time it hits a customer that had one check paying multiple invoices, it does not apply the amount to any of the invoices. When I look at the file using LockBox Maintenance and move to these rows I see values for: Deposit Date Check Amount Check Number Customer ID Row Type Indicator Invoice Number Invoice Apply Amt Transaction Description These are the fields that are mapped.
