• What is the cause and solution for SAP error message RSR_EXPLAIN028 - No exc. aggr. in HANA/BWA for constant &1: non-cumulative context ?

  The SAP error message RSR_EXPLAIN028 indicates that there is an issue with the aggregation of a constant in a non-cumulative context when using SAP HANA or BWA (Business Warehouse Accelerator). This error typically arises in the context of reporting or querying data in SAP BW (Business Warehouse) when the system is unable to perform the expected aggregation due to the nature of the data being queried.
  Cause:
  
  
  Non-Cumulative Key Figures: The error often occurs when you are trying to aggregate a non-cumulative key figure (like stock levels) in a context where it does not make sense to do so. Non-cumulative key figures are not meant to be summed over time or other dimensions.
  
  
  Constant Values: The error message specifically mentions a "constant," which suggests that the query is trying to aggregate a constant value that is not defined in a way that allows for aggregation in the context of the query.
  
  
  Query Design: The design of the query or the InfoProvider may not be set up correctly to handle the aggregation of the specified key figure.
  
  
  Solution:
  
  
  Review Key Figure Settings: Check the settings of the key figure in the InfoObject. Ensure that it is correctly defined as cumulative or non-cumulative based on its intended use.
  
  
  Adjust Query Design: Modify the query to ensure that it does not attempt to aggregate non-cumulative key figures inappropriately. This may involve changing the context of the query or the way the key figures are being used.
  
  
  Use of Constants: If you are using constants in your query, consider whether they are necessary and how they are being applied. You may need to adjust the logic to avoid aggregating constants in a non-cumulative context.
  
  
  Check Aggregation Levels: Ensure that the aggregation levels in your query are appropriate for the data being analyzed. Sometimes, adjusting the levels can resolve the issue.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance on handling non-cumulative key figures and constants in queries.
  
  
  Related Information:
  
  SAP BW Documentation: Review the official SAP BW documentation for best practices on designing queries and handling key figures.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  By following these steps, you should be able to identify the root cause of the RSR_EXPLAIN028 error and implement a solution to resolve it.
