hi
Lockbox is a process provided by a bank where the customer remits his payment to a PO Box at your bank, the bank deposits the check in your account and enters the remittance data from the customer. Then the bank sends the data to you electronically for you to import and apply in SAP-AR.
The structure that the bank uses is usually one of two formats. BAI will provide you the customer information and the check amount but no invoice remittance data. Usually cheaper and works well for a business where customers are paying only one invoice at a time.
BAI-2 offers remittance data but the bank charges more for the service because they have to enter more info.
Look at structures FLB** to see the transfer data. 
When the bank sends the customer payment data you use Treasury function FLB2 to import and then process the payments. This process attempts to determine where to apply the payment and will post directly against an invoice, an account to a customer or if it can't even determine the customer it posts into a clearing account (configured) to be resolved.
Purpose
Lockbox is a service offered by American banks in which banks collect and process customer payments to reduce processing time. The system can handle both lockbox file formats offered by banks, namely, BAI and BAI2.
Process Flow
A company can create accounts called ‘lockbox’ accounts at its bank (or banks) that act as payment collection accounts for customer payments.  The company then informs their customers that all open item payments for their accounts must be submitted to one of the established bank lockbox accounts.  The bank collects these payments along with the customers’ remittance information that indicates what open items the customer payments intend to clear.  Data entry clerks at the bank manually enter the information into an electronic file for transmission to the company to which the lockbox account belongs. These files are typically transferred nightly to the various lockbox owners (companies).  The files adhere to one of two standard banking industry transmission formats (BAI and BAI2), both of which are supported in the system.
BAI and BAI2 formats differ in their level of information detail.  BAI does not separate out the incoming check line items by invoice subtotal reference.  Conversely, BAI2 splits the check total into separate invoice references and associated payment amounts. As a result, your ‘hit rate’ percentage of payment-invoice matching from each transmission is likely to be higher when using BAI2 rather than BAI formats.
