  Complex Queries: When building complex queries or reports, it’s easy to inadvertently add too many fields, especially if you are combining multiple data sources or using multiple filters.

  Reduce the Number of Fields: Review the selection criteria and reduce the number of fields being used. Focus on the most relevant fields necessary for your analysis or reporting.
  Optimize Queries: If you are using a query designer, try to simplify the query by removing unnecessary fields or filters. Consider breaking down complex queries into simpler ones.
  Check System Limits: Consult the SAP documentation or your system administrator to understand the specific limits for your version of SAP. This can help you design your queries within the allowed parameters.
  Use Variables: Instead of selecting multiple fields directly, consider using variables or parameters that can dynamically filter the data based on user input.
  Consult SAP Notes: Check for any relevant SAP Notes or updates that might address this issue or provide guidance on best practices for query design.
