What are the steps for lock box setting?

Lock Box setting:
There are three lockbox settings:

• Defining lockboxes
• Defining control parameters
• Defining posting data

Transaction: OB10
In this transaction, you define your lockbox accounts at the house banks. Thus, on the outgoing invoice you can inform your customer of the lockbox to which payment is to be made. By specifying this, you can optimize the payment transactions.

To configure the lockboxes first specify the lockbox links (company code; key of the lockbox to which the customer is to pay; house bank ID; lockbox number at your house bank). Second enter a remit to address that will appear on the customer invoice.

Define Control Parameters:
SPRO -> Treasury -> Cash Management > Business Transactions -> Lockbox -> Define Control Parameters

Transaction: OBAY
The top "Record format' settings are unnecessary for BAI2 format, and should be left blank.

Procedure - LOCKBOX (currently the only supported procedure in standard system)

Record Format - BAI or BAI2

Record Format Parameters: (Required for BAI Only)
Document # length - length of the document # used to locate the open item
Number of document numbers in record type 6 - maximum # of documents in detail record
Number of document numbers in record type 4 - maximum # of documents in overflow record

Posting Parameters:
G/L Account Postings: Identifies whether G/L Posting is created.

G/L Account Posting Type: (1) = Posting / Check or (2) Posting / Lockbox
Incoming Customer Payments: Identifies whether to post to customer accounts also.

Insert Bank Details: Create batch session to update customer record with new bank details.

Define Posting Data:
Treasury -> Cash Management -> Business Transactions -> Lockbox -> Define Posting Data

Transaction: OBAX
The lockbox is defined with respect to a 'Destination' and 'Origin" identifier combination. Each lockbox must have its own unique Destination and Origin combination, and also must be defined for a single company code in configuration. The bank must transmit the file with the Destination, Origin and Lockbox identifiers in the exact format as they have been created in SAP lockbox configuration. Otherwise, the file will be improperly read by the lockbox and posting will not properly occur.

Bank Account Number - enter the bank (g/l) account for bank account posting
Bank (Payment) Clearing Account - enter the lockbox clearing account

Execution of Lockbox Program
The lockbox program can be accessed using transaction FLB2 or program RFEBLB00.

In the PRD environment a variant exists for each lockbox file. For test purposes it is easiest to copy the PRD variants, changing only the location of the lockbox file. However, Before executing the lockbox program please confirm that each of the fields in the above slide is completed as indicated.

Import into Bank Data Storage – this field should be selected so the lockbox file will be imported into the bank storage data. This ensures that the same lockbox file cannot be accidentally imported more than once (based on Origin, Destination, Date and Time values).

PC Upload – this field should be selected if the lockbox file resides on the users PC rather than in a UNIX directory.

Lockbox File – enter the location of the lockbox file in this field. The location may be either on the users PC or in the UNIX directory.

Procedure – this field should always be populated with LOCKBOX.

Input Record Format – this field should always be populated with BAI2.

Invoice Numbers – this field should always be populated with a '1'. This field offers four standard open item identification algorithms.
1 – match on document number (BELNR)
2 – match on reference number (XBLNR)
3 – match on document number first, if not found then on reference number
4 – match on reference number first, if not found then on document number

Enhanced Invoice No. Check – this field should not be selected. If selected it allows postings to be made across customer worklists.

Algorithm: checks with advice and Algorithm: checks without advice – these fields should be populated with 001. These fields determine whether cash that does not find an appropriate open item should be posted as 'On Account cash', or be applied against oldest open items on the account.

Account assignment fields – these fields should be left blank. The values entered in the fields are defaulted on the postings created by the lockbox program.

Print Control – this field should be selected so the lockbox reports will be output.
