SAP Error Message - Details

• Message type: E = Error

• Message class: RSPLS_CR - Messages on Characteristic Relationships/Data Slices

• Message number: 027

• Message text: Maximum number of &1 characteristic combinations exceeded

What causes this issue?

In characteristic relationship definition for InfoCube '&V2&', '&V1&' is
set as the maximum number of characteristic relationships that can be
generated according to the default value. However, according to the
parameters currently set, the number of combinations to be generated is
'&V3&'.

System Response

The combinations cannot be generated.

How to fix this error?

Check Customizing for the query or planning function. It is probable
that the selections determined in the filter are not restrictive enough.
If necessary, you can increase the maximum number of default
combinations in the characteristic relationships accordingly.

Procedure for System Administrators

• What is the cause and solution for SAP error message RSPLS_CR027 - Maximum number of &1 characteristic combinations exceeded ?

  The SAP error message RSPLS_CR027, which states "Maximum number of &1 characteristic combinations exceeded," typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when working with queries or data models that involve characteristics and their combinations. This error indicates that the number of characteristic combinations that can be processed has exceeded the predefined limit.
  Cause:
  
  
  High Cardinality: The error is often caused by a high number of unique combinations of characteristics in a query or data model. For example, if you have multiple characteristics (like customer, product, region, etc.) and each has a large number of unique values, the total combinations can grow exponentially.
  
  
  Configuration Limits: SAP has certain limits set for performance reasons. The maximum number of characteristic combinations is defined in the system settings, and exceeding this limit triggers the error.
  
  
  Query Design: Poorly designed queries that include too many characteristics or filters can lead to this issue. 
  
  
  Solution:
  
  
  Reduce the Number of Characteristics: Review the query or data model and try to reduce the number of characteristics being used. Focus on the most relevant ones for your analysis.
  
  
  Use Aggregation: Instead of querying at a detailed level, consider using aggregated data. This can significantly reduce the number of combinations.
  
  
  Filter Data: Apply filters to limit the data being processed. This can help in reducing the number of characteristic combinations.
  
  
  Check System Settings: Consult with your SAP Basis or BW administrator to check the system settings related to characteristic combinations. They may be able to increase the limit if appropriate.
  
  
  Optimize Query Design: Review the design of your queries. Ensure that they are optimized and do not include unnecessary characteristics or complex calculations that could lead to high cardinality.
  
  
  Use Variables: Implement variables in your queries to allow users to select specific values, which can help in reducing the number of combinations processed at once.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or patches related to this error.
  Performance Tuning: Consider performance tuning techniques for BW queries, such as using aggregates, optimizing InfoProviders, and ensuring proper indexing.
  Documentation: Refer to SAP BW documentation for best practices in query design and data modeling to avoid high cardinality issues.
  
  If the problem persists after trying these solutions, it may be beneficial to engage with SAP support for further assistance.
