1. Perform an action that should trigger a workflow in Manage Data or Employee Profile
2. Observe that the workflow is not triggered in the UI
3. Create a rule trace as per KBA 2257064 - Employee Central - Business Rule Execution Log and see that the rule correctly evaluates the condition, meaning the workflow should be triggered.

The record does not have a valid workflow Subject User Field populated, which is required for the workflow to trigger. The Subject User Field is configured in the Object Definitions and can be any user-defined field or ExternalCode.

1. Verify that the workflow Subject User Field is defined in the object definition in Configure Object Definitions and confirm which field is selected (externalCode or any other user field)
   
   
2. Ensure the field defined as workflow Subject User Field is populated before submitting the data in Manage Data or via Employee Profile
3. Test the workflow functionality after correcting the field and monitor for successful triggering.
