Positive pay is a fraud detection service where a company provides its bank with a list of issued checks, including check numbers and amounts. When checks are presented for payment, the bank matches the check information to the list. If there is no match, the check is not paid. To implement positive pay, a company needs to work with its bank to determine the required file format for the check information. Then it can create a program to extract the check data from SAP and generate a file in the required format to transmit to the bank.

Positive pay - An Overview
• What is Positive Pay?
• Positive Pay is an automated fraud detection service offered by the US Commercial Bank.
• Positive pay is informing the bankers about the checks your company has issued.
How does Positive Pay work?
• For instance, ABC Company issues approximately 500 checks every Monday. After the checks are
cut, ABC Company transmits to their bank, a list of the checks that are being issued (check number
and dollar amount etc...). This list is imported into Bank's computer.
Later, when the checks are presented to Bank for payment, Bank matches each check presented against
ABC's previously transmitted lists. If the presented checks' numbers and amounts appear on a previously
submitted list, the check is sent through for payment. If both items do not match, the check is not cleared.

2. Positive pay - An Overview
• How would be the positive pay file?
Positive pay file structure is specific to the banks. Each bank has its own format. We need to get
information from the bank about their file format with details of header, record count, amounts etc., A
customized program to map these fields is required. After the automatic payment run, if this program is
executed, it will generate the positive pay file in the bank's required format..
• There is a standard T Code – FCHX, program RFCHK0E0 which extracts the information
of checks issued from the system but the file format which it creates is different than what is
required by the Bank. It also stores the file on the SAP Application server.
• RFCHKE00 program reads the data from PAYR, BNKA, T012 (House bank) and T012K (House bank
Account).

3. Positive pay - An Overview
Step-1: Copy the program RFCHKE00 and create a ZRFCHKE00.
Step-2: Create Z T-code (Ex:-ZFCHX). We need to take the help of ABAPer to create the Positive
pay file as per the format specified by the Bank.
Step-3: After issuing the checks (Manual checks issue or through APP), we have to execute T-code
ZFCHX.
Step-4: Once the T-code ZFCHX has been executed, the program ZRFCHKE00 will extract the data
in to a Positive Pay file which we have mapped
with the help of ABAPer as per the format specified by the
bank.
Step-5: The file which has got generated in Step-4 will be stored in SAP Directories (T-code AL11) or
as per the file path we specify.
Step-6: Positive Pay information can be transmitted to Bank through processes like FTP, EDI
(IDOCs) as these are secure more sophisticated than others
