Smart SAP Assistant

• What is the cause and solution for SAP error message RSR_EXPLAIN005 - No exc. aggregation in HANA/BWA for constant &1. Calculation before aggr. ?

  The SAP error message RSR_EXPLAIN005 indicates that there is an issue with the execution of a query in SAP BW (Business Warehouse) when it is trying to perform an aggregation operation in HANA or BWA (Business Warehouse Accelerator). The specific message "No exc. aggregation in HANA/BWA for constant &1. Calculation before aggr." suggests that the system is unable to perform the expected aggregation due to the presence of a constant value in the query.
  Cause:
  
  
  Constant Values in Query: The error typically arises when the query contains constant values that cannot be aggregated directly in HANA or BWA. This can happen if the query is trying to perform calculations on constant values before the aggregation step, which is not supported in the current context.
  
  
  Query Design: The design of the query may not be optimal for the underlying data model or the capabilities of HANA/BWA. If the query is trying to perform complex calculations or aggregations that are not supported, it can lead to this error.
  
  
  Data Model Issues: There may be issues with the underlying data model, such as missing or incorrect aggregations defined in the InfoObjects or InfoProviders.
  
  
  Solution:
  
  
  Review Query Design: Check the query design in the Query Designer. Look for any constant values or calculations that are being performed before aggregation. If possible, modify the query to avoid using constants or to perform calculations after the aggregation.
  
  
  Use Variables: Instead of using constant values directly in the query, consider using variables. This allows for more flexibility and can help avoid issues with aggregation.
  
  
  Check Aggregation Settings: Ensure that the aggregation settings for the InfoObjects and InfoProviders are correctly defined. Make sure that the necessary aggregations are in place to support the calculations being performed in the query.
  
  
  Test with Simplified Query: Create a simplified version of the query to isolate the issue. Remove complex calculations and constants to see if the error persists. This can help identify the specific part of the query causing the problem.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or documentation that may address this specific error. SAP frequently updates its knowledge base with solutions for common issues.
  
  
  Performance Considerations: If the query is complex, consider optimizing it for performance. This may involve restructuring the query or using different aggregation techniques.
