  Reduce Grouping Fields: Review the query and reduce the number of fields you are using for grouping. Focus on the most relevant fields that provide the necessary insights.
  Aggregate Data: If possible, aggregate data at a higher level before performing the query. This can help reduce the number of grouping fields needed.
  Modify Query Design: Consider redesigning the query to use fewer characteristics or to break it down into multiple queries that can be executed separately.
  Check Query Properties: In the query designer, check the properties of the query to ensure that unnecessary fields are not included in the grouping.
  Consult Documentation: Refer to SAP documentation or help resources for specific limits on grouping fields for your version of SAP BW/BI.
