Validates and processes outbound transactions that require approval from an external credit system before execution.

The External Credit Approval Required flag in the External Customer Account Input (STDCRACC) screen specifies whether external credit approval is required for the debit account.

If the flag is set as Yes, then the External Credit Approval System is picked up from the account maintenance.

An ECA request XML is prepared that includes the details like a debit account, amount to be debited, and charge components with charge amount to be debited.

A record is logged in to the ECA Queue. The request is in ECA Queue with status as Pending till the final response (Accept / Reject / Seizure) is received.

If the debit account type is Vostro or if the transaction is a Reverse Message transaction and if the debit account level ECA Check Required flag is enabled, then ECA request is generated and sent out to the ECA system.

The ECA request reference / ECA status values at transaction level gets updated with the ECA queue reference and the latest status of the ECA check.

After receiving the response from the ECA system, the transaction gets processed further based on the response.
