• What is the cause and solution for SAP error message RSR_EXPLAIN016 - No exception aggr. in HANA/BWA due to free characteristic currency/unit ?

  The SAP error message RSR_EXPLAIN016 indicates that there is an issue with the aggregation of data in HANA or BWA due to the presence of free characteristics that are defined in currency or unit of measure. This typically occurs in the context of SAP BW (Business Warehouse) when trying to execute a query that involves aggregating data that includes free characteristics that are not compatible with the aggregation process.
  Cause:
  
  Free Characteristics: The error arises when a query includes free characteristics that are defined in currency or unit of measure. These characteristics can lead to ambiguity in how the data should be aggregated.
  Aggregation Rules: In SAP BW, certain characteristics (like currency or unit) require specific aggregation rules. If these rules are not properly defined or if the characteristics are not compatible with the aggregation, the error will occur.
  Data Model: The underlying data model may not support the aggregation of the specified characteristics due to the way the InfoObjects are defined or how the data is structured.
  
  Solution:
  
  Review Query Design: Check the query design in the Query Designer. Ensure that free characteristics that are defined in currency or unit of measure are not included in the query unless necessary.
  Remove Free Characteristics: If possible, remove the free characteristics that are causing the issue from the query. This can help in avoiding the aggregation problem.
  Aggregation Settings: Review the aggregation settings for the InfoObjects involved. Ensure that the aggregation behavior is correctly defined for currency and unit of measure characteristics.
  Use Key Figures: Instead of using free characteristics, consider using key figures that are already aggregated or that have defined aggregation behavior.
  Check Data Model: Ensure that the data model supports the required aggregations. This may involve checking the InfoProviders and ensuring that they are correctly set up to handle the characteristics in question.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of BW or HANA you are using for any additional guidance or updates regarding this error.
