Messages Received with ‘DUPL’ in Business Header

  • On uploading any pain.013 message, system has to check whether it is received with DUPL tag in the business header.
  • If yes, before treating it as an inbound payment, validation is to be done whether a payment is received with the same Instruction ID before.
  • If yes, based on the transaction status pacs.002 message needs to be generated and send out. If a similar transaction is not received before, the current pain.013 message needs to be treated as a new RFP and needs to be processed as an inbound RFP.
