This is applicable to the Pass-through Cross Border payment debit accounting entry posting processing for transactions created due to Reverse MT 103/202 messages.

The ECA - External Credit Approval request will be sent to the ECA system for the debit account / debit amount. This is done after the Pricing processing step (before doing accounting entry posting processing step).

If the ECA system response is positive, then the debit accounting entry posting will be done along with credit accounting entry posting. The accounting entries will get handed off to accounting system. The transaction will get processed further. i.e. network cutoff, payment message generation, advice message generation and notification generation steps will get triggered. Queue action log will be populated for the ECA request/response processing.

If the ECA system response is negative, then the transaction cancellation processing will get triggered.
