  The SAP error message SWF_EXP_001199 indicates that a parameter has been passed multiple times to a method in a workflow. This can occur in SAP Business Workflow when a method is called with the same parameter more than once, which is not allowed.
  Cause:
  The error is typically caused by:
  
  Duplicate Parameter Passing: The same parameter is being passed multiple times in the workflow method call.
  Incorrect Workflow Configuration: The workflow might be incorrectly configured, leading to the same parameter being referenced multiple times.
  Custom Development Issues: If there are custom methods or enhancements, they might be incorrectly implemented, leading to this error.

  Check Workflow Configuration:
  
  Review the workflow definition and ensure that parameters are not being passed multiple times.

  Debugging:
  
  Use the workflow log to trace the execution and identify where the duplicate parameter is being passed.
  You can also use transaction SWI1 (Work Item Selection) to analyze the workflow instance and see the parameters being passed.
