Trigger workflow in S4 Central Finance System for release of sales order via DCD

Hi Experts,

As most of you know, when we are creating a sales order with credit block in ECC System, it will create a DCD ( documented credit decision document) in S4 Central Finance System. My requirement is I need to trigger custom workflow, when DCD is created. For triggering workflow, I need to find the event that is getting triggered when DCD is created. For this I switched on the trace using SWELS. I ran the Sales Order Transaction in ECC, and DCD got created in S4 HANA. But no event got created in S4 HANA.

How can I proceed further?

1. Is there any BADI where we can write custom code to trigger the workflow. If yes, please provide.

2. Is there any other way to implement the workflow for this scenario?

SAP doesn't have standard workflow for the same.
