ESS Job Completion Business Event

Summary:

We have a requirement to trigger an OIC Intergration once the Pick Confirm process (ESS Job in ERP Cloud) completes

Content (required):

I have a requirement to integrate with a 3PL vendor. Once an Order has been pick confirmed, we need to send the order and related details to them.

The standard Pick Confirm business event fires for every order/line in the the Pick List. For e.g., if a Pick List has 2 orders with 2 lines each, a total of 4 events is raised. However, I need to generate only 2 messages (1 per order). Is there a way I can achieve this?
