• What is the cause and solution for SAP error message SWL_WP037 - No handler has been maintained for the selected handler category ?

  The SAP error message SWL_WP037, which states "No handler has been maintained for the selected handler category," typically occurs in the context of SAP Workflow. This error indicates that there is no defined handler for the specific category of workflow that you are trying to execute or process.
  Cause:
  
  Missing Handler Configuration: The most common cause of this error is that the workflow handler has not been configured in the system. Each workflow category requires a specific handler to process the workflow tasks, and if this handler is not set up, the system cannot proceed.
  Incorrect Workflow Category: The workflow category being used may not match any of the configured handlers, leading to this error.
  Transport Issues: If the workflow configuration was transported from another system, it is possible that the handler settings were not included in the transport request.
  
  Solution:
  
  
  Check Workflow Configuration:
  
  Go to transaction SWFVISU (Workflow Visualization) or SWDD (Workflow Builder) to check the workflow definition and ensure that the correct handler is assigned to the workflow category.
  Verify that the handler is correctly defined in the system.
  
  
  
  Maintain Handlers:
  
  Use transaction SWF_CATALOG to maintain the workflow handlers. Ensure that the necessary handlers for the workflow category are created and activated.
  If you are missing a handler, you may need to create a new one or adjust the existing ones to ensure they are correctly linked to the workflow category.
  
  
  
  Check for Transport Issues:
  
  If the workflow was transported from another system, ensure that all necessary objects, including handlers, were included in the transport request.
  You may need to manually configure the handlers in the target system if they were not transported.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific workflow you are working with. There may be specific instructions or prerequisites for setting up the workflow handlers.
