Creditor FI Incoming Credit Transfer Accept without Posting (TCH)

Variation of the main Creditor FI Incoming Credit Transfer flow showing scenarios where the payment may be accepted before all checks are completed.

Use Case Summary

The funds are not credited to the creditor’s account until the checks have completed successfully. This scenario is only permitted in the cases where the creditor FI needs additional time to review the payment for legal or compliance purposes.

Normally when services that are invoked within the Pre-Check set complete they may respond with either an Accept (success) or Reject (fail) response. An interim Pending (or hold) response indicates that the service is not ready to complete yet, and a further Accept or Reject response will follow. This would typically be used by the Fraud Screening and Sanctions Screening services when further (possibly manual) checks are required.

The accept without posting response is triggered when any Pre-Check service returns a Pending response. It can also be triggered if a configured timeout period elapses while waiting for responses from designated services (other mandatory services, such as Accounting, must complete before a timeout will be handled).

The creditor FI incoming credit transfer accept without posting case consists of the following processing steps:
  • FTM for Immediate Payments receives a payment from the CSM.
  • The payment is validated and checked for duplicate.
  • Next, the set of services that are configured for the Pre-Check set are invoked. This set should just perform validation checks to determine whether the payment can be accepted.
  • The accept without posting scenario is triggered by either a timeout or a Pending response from a Pre-Check service.
  • Next, the set of services that are configured for the Pre-Accept without Posting set are invoked.
  • On successful completion of the Pre-Accept without Posting services, FTM for Immediate Payments sends a positive acknowledgment to the CSM, confirming that the payment has been accepted without posting by the bank.
  • The CSM confirms the acknowledgment by sending a status message.
  • FTM for Immediate Payments will then wait until a final response is received from all the Pre-Check services.
  • If the Pre-Check services complete successfully, the set of services (if any) that are configured for the Post-Accept without Posting success set are invoked. These will typically include an Accounting Credit and a notification to the Channels interface, which in turn may provide a notification to the (creditor) client .
  • Also, if the Pre-Check services complete successfully, the creditor FI initiates a "Payment Acknowledgement by Receiver" flow to notify the debtor FI that the payment has completed successfully.
  • If the Pre-Check services do not complete successfully, the set of services (if any) that are configured for the Post-Accept without Posting fail set are invoked.

Note: The diagram illustrates sets of optional services within parallel groups for each of the service sets Pre-Check, Pre-Accept without Posting, Post-Accept without Posting success, Post-Accept without Posting fail. The services shown depict services that may typically be included in the set. The actual services to be invoked, and whether they are invoked in parallel or serially is determined by configuration.
