• What is the cause and solution for SAP error message RSR_EXPLAIN004 - No exc. aggr. in HANA/BWA for constant &1. Aggregation not supported. ?

  The SAP error message RSR_EXPLAIN004 indicates that there is no exception aggregation available in HANA or BWA for a constant value. This typically occurs when you are trying to perform an aggregation operation on a constant value that is not supported by the underlying database (HANA or BWA).
  Cause:
  
  Unsupported Aggregation: The error arises when the query attempts to perform an aggregation on a constant value that does not have an associated exception aggregation defined in the InfoObject or the data model.
  Data Model Configuration: The data model may not be configured to handle exception aggregations for the specific characteristic or key figure being queried.
  Query Design: The query may be incorrectly designed, leading to the attempt to aggregate a constant value that cannot be processed.
  
  Solution:
  
  
  Check Aggregation Settings:
  
  Review the InfoObject settings in the SAP BW system to ensure that exception aggregation is defined for the relevant key figures.
  If necessary, modify the aggregation settings to include exception aggregation for the constant value.
  
  
  
  Modify the Query:
  
  Adjust the query design to avoid using constant values that require exception aggregation. Instead, use variables or other dynamic values that can be aggregated properly.
  Ensure that the query does not attempt to aggregate on fields that are not meant to be aggregated.
  
  
  
  Review Data Model:
  
  Check the data model in HANA or BWA to ensure that it supports the required aggregations. If the model is not set up correctly, consider redesigning it to accommodate the necessary aggregations.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation for specific guidelines on exception aggregation and supported operations in HANA/BWA. This can provide insights into how to configure your data model and queries correctly.
  
  
  
  Testing:
  
  After making changes, test the query again to ensure that the error is resolved and that the expected results are returned.
