Lockbox process

The predominant way payments are made in US is by checks. Lockboxs help in speedy deposit of funds and clearance of customer accounts. Lockboxs are special depository accounts set up at a bank to which customer remit their invoice payments.

Banks daily than submit company’s an electronic file listing all deposits and invoices that are paid against. Company’s than upload these files in SAP and update their balance and clear customers i.e. A/R accounts.

Some company’s setup single lockbox whereas others set up lockboxs at different locations thought the country in order to decrease the time it takes to receive the customer payments.

Lockbox File Formats

SAP supports both US lockbox file formats – BAI & BAI2.Each bank has its own standard BAI and BAI2, hence configuration and testing needs to be done depending on bank file configuration.

Hence if you are not comfortable with bank file format either you can approach them to modify it depending on your requirement else ABAP can help in writing a preprocessing program and make file fit with SAP standard format.

Difference between BAI and BAI2

BAI2 is advised as because it has greater probability of producing automatic matches in the processing and because it allows one to record deduction information and create proper residual postings.

Relationship between EBS and Lockbox

Assume on Day 1 company receives Lockbox file from bank and on Day 2 receives EBS file.

Day 1 When the bank receives a check from customer with remittance information its sends it in Lockbox file. Lockbox file when processed will generate below accounting posting

          Dr Bank Clearing account - incoming

     Cr Lockbox Clearing Account

          Dr Lock box clearing account

     Cr Customer account (customer sub ledger)

Day 2 when the check is cleared in bank, it appears in EBS. EBS when processed produces below accounting entry

Dr Bank Main GL

          Cr Bank Clearing Account - incoming

Lockbox file processing

SAP gives option of using one of the two standard algorithms for lockbox processing. A common misrepresentation is that one can create own algorithm which is not correct. We can only use the pen delivered by SAP. Program RFEBLB00 is the processing program. Documentation can be viewed for this program from SE38 transaction code. This program contains lot many user exits whether one can add any additional business logic.

Two algorithms that are used are 001 and 003. If file contains checks that cannot be applied against specific invoice but for which customer account is known, SAP posts them on the customer account without reference to any specific invoice. Using algorithm 003, SAP distributes the check across open invoices, beginning at the oldest invoice and working its way forward until the check amount is fully distributed.

1)   Sap file generation

            Use Test Lockbox Generation Programs RFEBLBT2 to generate BA12 format and RFEBLBT3 for IDOC format. These programs will generate customer open items and a lockbox file for processing.  Utilize program RFEBKA96 to delete loaded test data
