• What is the cause and solution for SAP error message SWN152 - Handlers are only permitted for receiver determinations using handlers ?

  The SAP error message SWN152 indicates that there is an issue with the configuration of the SAP Workflow Notification (SWN) system, specifically related to the use of handlers in receiver determinations. This error typically arises when you attempt to use a handler in a context where it is not permitted.
  Cause:
  The error occurs when:
  
  You are trying to use a handler in a receiver determination that does not support it.
  The configuration of the receiver determination is incorrect or incomplete.
  The system is expecting a direct assignment of a receiver rather than a handler.
  
  Solution:
  To resolve the SWN152 error, you can follow these steps:
  
  
  Check Receiver Determination Configuration:
  
  Go to the transaction code SWN1 (Workflow Notification) and review the configuration of your receiver determination.
  Ensure that you are using the correct type of receiver determination that supports handlers.
  
  
  
  Review Handlers:
  
  If you are using a handler, ensure that it is correctly defined and that it is compatible with the receiver determination you are using.
  Check the implementation of the handler to ensure it is functioning as expected.
  
  
  
  Use Direct Receiver Assignment:
  
  If the context does not allow for handlers, consider using a direct assignment of the receiver instead of a handler.
  Modify the receiver determination to specify the receiver directly.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific version of SAP you are using for any additional guidance on configuring handlers and receiver determinations.
  
  
  
  Testing:
  
  After making changes, test the configuration to ensure that notifications are being sent correctly without triggering the SWN152 error.
