RSOH020 - Details

• 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
