Why Are Some triggered_send_id Values Associated With Multiple activity_name Values?

Question

Each triggered_send_id value should only be associated with one activity_name value. However, in my destination, some triggered_send_id values are associated with multiple activity_name values. How is this possible?

Environment

Connector: Salesforce Marketing Cloud

Answer

When you copy a journey in Salesforce, the new draft journey retains the triggered_send_id value associated with the old journey until you activate it. However, even as a draft, Salesforce returns a unique activity_name value for the new journey. As a result, a triggered_send_id value can be associated with multiple activity_name values if you copy a journey without activating the new draft.
