There are two ways Customer and Bank Integration can be done and those are follows,

  1. ABAP Package  ( File Extraction (CSV,TXT File Format) )
  2. ABAP+PI Package ( IDOC Processing via PI Server- IDOC Basic Type : PEXR2002  and Message Type : PAYEXT )

  1. ABAP Package:
  • ABAPER will develop Z Report, where customer finance need to provide input’s and execute, so that Bank Specification format file will get extracted and same file will be placed in Bank FTP Server Location.
  • If Bank contains only SFTP server not FTP then customer will purchase External software to push File to bank end.
  • Even Bank has some sort of software kit, they will install in customer landscape to push file to Bank SFTP Location but this approach will be discussed with Bank only.

Pro’s:

  • File Encryption can be done using Bank external software.
  • Payments Batching can be done in File level.
  • User visibility will be there and duplication payments can’t be extracted using Z Report.

Cons:

  • Monitoring won’t be there.
  • SSL  Security  won’t be there.
  • Once File Successfully reached to bank then Customer won’t get  Acknowledgement from Bank end using this medium.

Flow:

          Z REPORT –>Extract File in Application Server –> Encrypt File Application Server –> Push File into Bank FTP Server. 
