• What is the cause and solution for SAP error message WK320 - Preview activated ?

  SAP Error Message:
  
  WK320 Preview activated
  
  Meaning / Cause:
  The message WK320 Preview activated appears in SAP Workflow when you are running a workflow in preview mode. Preview mode is a special mode used to simulate or test the workflow without actually executing the workflow tasks or sending real notifications. It allows you to check the workflow logic, steps, and paths without affecting the live system or triggering real actions.
  This message is informational and indicates that the workflow is currently running in preview mode.
  
  When does it occur?
  
  When you start a workflow in preview mode from the SAP GUI or via transaction SWUS (Workflow Builder) or SWI1 (Workflow Log).
  When you use the "Test" or "Simulate" options in the workflow tools.
  When the workflow container or the workflow runtime environment is set to preview mode.
  
  
  Solution / How to handle:
  
  If you want to actually execute the workflow (i.e., trigger real tasks, send notifications, update data), you need to run the workflow in normal mode, not preview mode.
  To do this, start the workflow without selecting the preview option.
  If you are testing or debugging, preview mode is useful and no action is needed.
  If you see this message unexpectedly during normal workflow execution, check if the workflow was accidentally started in preview mode or if any user exit or custom code forces preview mode.
