  Error Message
  W_CB408: Receivers missing in Event Container
  
  Cause
  This warning message occurs in the context of Workflow in SAP. It indicates that the workflow event container does not contain any receiver(s) for the workflow step or event. In other words, the workflow is expecting one or more receiver(s) (users, organizational units, roles, etc.) to be assigned to a particular step or event, but none have been determined or passed into the event container.
  Common causes include:
  
  The method or event triggering the workflow does not supply the receiver information.
  The binding of the receiver container element is missing or incorrect.
  The organizational assignment or user determination logic is not set up or is failing.
  The workflow step is configured to require receivers, but none are found or assigned.
  
  
  Explanation
  In SAP Workflow, the Event Container holds data related to the event that triggers the workflow. One important piece of data is the receiver(s) who will perform the workflow task. If the event container does not have this information, the workflow cannot proceed properly, hence the warning.
  
  Solution
  
  
  Check Event Container Binding:
  
  Go to the workflow builder (transaction SWDD).
  Open the workflow and check the event container of the triggering event.
  Verify that the receiver container element (often named something like RECEIVERS, RECIPIENTS, or TASK_RECEIVERS) is correctly bound and populated.
  
  
  
  Verify Receiver Determination:
  
  Check the method or event that triggers the workflow to ensure it passes the receiver information.
  If the receiver is determined dynamically (e.g., via organizational assignment or user exit), verify that the logic is working correctly.
  
  
  
  Check Organizational Assignment:
  
  If the receiver is determined via organizational objects (e.g., positions, organizational units), ensure that these assignments are maintained correctly in the system.
  
  
  
  Adjust Workflow Step Settings:
  
  If the workflow step requires receivers, but none are found, consider:
  
  Changing the step to not require receivers (if appropriate).
  Adding default receivers or fallback logic.
  
  
  
  
  
  Debugging:
  
  Use transaction SWEL to check the event log.
  Use transaction SWI1 to monitor workflow instances.
  Debug the workflow container to see why receivers are missing.

  Aspect
  Description

  Solution
  Verify and correct receiver determination logic, container binding, and organizational data.
  
  
  Tools
  SWDD, SWEL, SWI1, PFTC for analysis and correction.
