  The SAP error message CH402 indicates that a user is not authorized to perform a specific workflow task. This error typically arises in the context of SAP Business Workflow, where certain tasks require specific authorizations that the user may not possess.
  Cause:
  
  Authorization Issues: The user does not have the necessary authorizations assigned to their user profile to execute the workflow task.
  Role Assignment: The user may not be assigned to the appropriate roles that include the necessary permissions for the workflow.
