• What is the cause and solution for SAP error message RSPLS_CR026 - &1 characteristic combinations generated ?

  The SAP error message RSPLS_CR026 typically relates to issues with characteristic combinations in the context of SAP BW (Business Warehouse) or SAP BW/4HANA. This error indicates that there are too many characteristic combinations generated for a particular query or InfoProvider, which can lead to performance issues or exceed system limits.
  Cause:
  
  High Cardinality: The characteristics involved in the query have a high cardinality, meaning there are many unique combinations of values. This can happen if you have many characteristics with a large number of possible values.
  Query Design: The design of the query may be such that it inadvertently generates a large number of combinations, especially if multiple characteristics are included in the query without proper filtering.
  Data Volume: The volume of data being processed can also contribute to the generation of excessive combinations, especially if the data model is not optimized.
  
  Solution:
  
  
  Optimize Query Design:
  
  Review the query and remove any unnecessary characteristics that are not needed for the analysis.
  Use filters to limit the data being processed, which can help reduce the number of characteristic combinations.
  Consider using variables to restrict the selection of data.
  
  
  
  Aggregate Data:
  
  If possible, aggregate the data at a higher level to reduce the number of combinations. This can be done by creating aggregates in the InfoCube or using summary tables.
  
  
  
  Check Characteristic Values:
  
  Analyze the characteristic values being used in the query. If there are many values that are rarely used, consider removing them or consolidating them into broader categories.
  
  
  
  Performance Tuning:
  
  Ensure that the InfoProvider is properly indexed and that statistics are up to date. This can help improve performance and reduce the likelihood of generating excessive combinations.
  
  
  
  System Configuration:
  
  Check the system settings related to the maximum number of characteristic combinations allowed. If necessary, consult with your SAP Basis team to see if adjustments can be made, but be cautious as this can have broader implications.
