  Error Message
  WK013: Function is not possible for class &
  
  Cause
  This error occurs in the SAP Workflow system when you try to perform a workflow function (such as triggering a workflow, changing workflow status, or executing a workflow step) on an object that belongs to a class for which the requested function is not supported or allowed.
  In SAP Workflow, objects are classified into classes, and each class has specific workflow functions defined. If you attempt to execute a function that is not defined or allowed for the object's class, the system raises this error.
  Common scenarios include:
  
  Trying to start or trigger a workflow for an object whose class does not have the workflow function assigned.
  Attempting to perform workflow operations on an object class that is not configured for workflow.
  Using a workflow function that is not implemented or supported for the particular object class.
  
  
  Solution
  To resolve the error WK013, follow these steps:
  
  
  Check the Object Class:
  
  Identify the class of the object on which the workflow function is being executed.
  You can check the object class in transaction SWO1 (Workflow Object Builder).
  
  
  
  Verify Workflow Functions for the Class:
  
  In SWO1, open the object class.
  Check the list of workflow functions (methods) assigned to this class.
  Confirm whether the function you are trying to execute is available and active for this class.
  
  
  
  Assign or Implement the Required Function:
  
  If the function is missing, you need to either:
  
  Assign an existing workflow function to the class.
  Implement a new workflow function (method) in the class that supports the required operation.
  
  
  
  
  
  Adjust Workflow Configuration:
  
  If the object class is not intended to support workflows, reconsider the workflow design.
  If workflows are required, ensure the object class is properly configured for workflow processing.
  
  
  
  Check Authorization and System Settings:
  
  Sometimes, missing authorizations or incorrect system settings can cause this error.
  Verify that the user has the necessary authorizations to execute workflow functions on the object class.
  
  
  
  Consult SAP Notes and Documentation:
  
  Check SAP Notes for any known issues or patches related to this error.
  Review SAP Workflow documentation for best practices on object class and function assignments.
