Messages Received with ‘DUPL’ Header

  • On uploading any pacs.008 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 pacs.008 message needs to be treated as a new payment and needs to be processed as an inbound payment.
