• What is the cause and solution for SAP error message WS801 - First select event ?

  SAP Error Message:
  
  WS801 - First select event
  
  Cause:
  The error message WS801 - First select event typically occurs in SAP Workflow when an attempt is made to process or trigger a workflow event without first selecting or defining the event that should start or influence the workflow. In other words, the workflow engine expects an event to be selected or specified before it can proceed, but none has been provided.
  This can happen in scenarios such as:  
  
  Trying to trigger a workflow without specifying the triggering event.  
  Missing or incorrect event linkage in the workflow definition.  
  Calling a workflow container or task without the required event context.
  
  
  Solution:
  To resolve the WS801 error, you should:
  
  
  Check the Workflow Event Configuration:  
  
  Ensure that the workflow has a properly defined start event or triggering event.  
  Verify that the event is correctly linked to the workflow template.
  
  
  
  Select or Specify the Event Before Triggering:  
  
  When manually triggering a workflow or testing it, make sure to select the appropriate event.  
  If triggering via code or function modules, ensure the event parameter is correctly passed.
  
  
  
  Review Workflow Binding and Event Linkage:  
  
  In the workflow builder (transaction SWDD), check the event linkage and ensure the event is correctly bound to the workflow container elements.  
  Confirm that the event is active and released.
  
  
  
  Check for Missing or Incorrect Event in Custom Code:  
  
  If the workflow is triggered programmatically (e.g., via SAP_WAPI_START_WORKFLOW or similar function modules), verify that the event ID is correctly provided.
  
  
  
  Activate and Release Events:  
  
  Use transaction SWETYPV to check event types and ensure the event is active and released.
