  Cause:
  
  Exceeding Characteristic Limit: The query may contain more characteristics than the system can handle. Each query has a limit on the number of characteristics that can be processed simultaneously.

  Review Query Design: Check the query design in the SAP BW Query Designer. Ensure that the number of characteristics used in the query does not exceed the system's limits.
  Optimize Characteristics: If possible, reduce the number of characteristics in the query. Consider whether all characteristics are necessary for the analysis you are performing.
  Check InfoObjects: Verify that the InfoObjects used in the query are correctly defined and activated. Ensure that they are relevant to the data being queried.
  Test with Fewer Characteristics: Try running the query with fewer characteristics to see if it executes successfully. This can help identify if a specific characteristic is causing the issue.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW you are using for any known limitations or additional troubleshooting steps.
