• What is the cause and solution for SAP error message WA400 - Event not correctly selected ?

  The SAP error message WA400: Event not correctly selected typically occurs in the context of Workflow or Business Event Management within SAP. This error indicates that the system could not find or correctly identify the event that was supposed to trigger a workflow or a process.
  
  Cause
  
  Incorrect or missing event linkage: The event that is supposed to trigger the workflow is either not defined, not active, or incorrectly linked.
  Event not registered: The event might not be registered in the system or the event linkage to the object is missing.
  Wrong event parameters: The parameters passed to the event are incorrect or incomplete.
  Event not released or active: The event might be created but not released or activated in the system.
  Incorrect event selection in workflow: The workflow definition might be referring to an event that does not exist or is not valid for the object type.
  
  
  Solution
  
  
  Check Event Definition:
  
  Use transaction SWETYPV (Event Linkage) to verify that the event is correctly linked to the business object.
  Ensure the event is active and correctly defined.
  
  
  
  Verify Event Registration:
  
  Use transaction SWO1 to check the business object and its events.
  Confirm that the event exists and is released.
  
  
  
  Check Workflow Event Linkage:
  
  In transaction PFTC or SWDD (Workflow Builder), verify that the workflow is triggered by the correct event.
  Make sure the event name and parameters match the event defined in the business object.
  
  
  
  Activate Event Linkage:
  
  If the event linkage is inactive, activate it in SWETYPV.
  
  
  
  Check Event Raising Code:
  
  If the event is raised programmatically (e.g., via function module SWE_EVENT_CREATE), verify that the correct event name and parameters are passed.
  
  
  
  Re-generate Event Linkage:
  
  Sometimes, re-generating or re-activating the event linkage can solve inconsistencies.
  
  
  
  Check Authorization:
  
  Ensure the user triggering the event has the necessary authorizations.
