• What is the cause and solution for SAP error message RSOH020 - You cannot use more than 16 characteristics (at the moment &3) ?

  The SAP error message RSOH020 indicates that you are trying to use more than 16 characteristics in a query or report, which exceeds the limit set by the system. This limitation is particularly relevant in the context of SAP BW (Business Warehouse) and reporting tools like BEx (Business Explorer).
  Cause:
  The error occurs when you attempt to create or execute a query that includes more than 16 characteristics in the selection criteria or in the query definition. This is a restriction in the SAP BW system to ensure performance and manageability.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Reduce the Number of Characteristics:
  
  Review the query and try to limit the number of characteristics to 16 or fewer. This may involve removing less critical characteristics or consolidating them.
  
  
  
  Use Hierarchies:
  
  If applicable, use hierarchies to group characteristics. This allows you to represent multiple values under a single characteristic, effectively reducing the number of characteristics used.
  
  
  
  Create Additional Queries:
  
  If you need to analyze data with more than 16 characteristics, consider creating multiple queries that focus on different aspects of the data. You can then combine the results as needed.
  
  
  
  Use Variables:
  
  Implement variables in your query to allow users to select values dynamically. This can help reduce the number of characteristics displayed at once.
  
  
  
  Check for Unused Characteristics:
  
  Sometimes, characteristics may be included in the query definition but not used in the report. Review the query to ensure that only necessary characteristics are included.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support resources for any updates or changes regarding limitations in your specific version of SAP BW.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific updates or patches related to this error message. SAP frequently releases updates that may address limitations or provide workarounds.
  Performance Considerations: Keep in mind that even if you manage to include more than 16 characteristics through workarounds, it may impact the performance of your queries. Always test the performance after making changes.
