How To Fix WL409 - Workflow '&' no. &: Element '_WF_Initiator' missing in workflow container

SAP Error Message - Details

• Message type: E = Error

• Message class: WL - Workflow: run-time messages

• Message number: 409

• Message text: Workflow '&' no. &: Element '_WF_Initiator' missing in workflow container

What causes this issue?

When the (sub)workflow '&V1&' (no. &V2&, step or definition no. &V3&)
was created, there was no initiator (element <ZH>_WF_Initiator</>) in
the workflow container.

System Response

The workflow was started without the element <ZH>_WF_Initiator</>.
This leads to problems if the workflow (or one of its subworkflows)
uses the element <ZH>_WF_Initiator</> as the agent of a task.

How to fix this error?

Make sure a binding has been defined for the element <ZH>_WF_Initiator
</> from the event which started the workflow to the container of the
workflow task '&V1&' (no. &V2&). The element <ZH>EVT_CREATOR</> of the
event container generally contains a user name or another
organizational unit which can be used for this binding definition.
When the workflow is started in dialog, this error should not occur
since the initiator is then set automatically by the appropriate
workflow transaction.
When a subworkflow is started, the initiator of the higher-level parent
workflow is used automatically.
