• What is the cause and solution for SAP error message RSR_EXPLAIN019 - No exception aggregation in HANA/BWA due to current member ?

  The SAP error message RSR_EXPLAIN019 indicates that there is an issue with exception aggregation in HANA or BWA (Business Warehouse Accelerator) due to the current member being processed in a query. This error typically arises when the system is unable to perform exception aggregation because the context of the current member does not allow for it.
  Cause:
  
  Current Member Context: The error often occurs when the current member in the query context does not support exception aggregation. This can happen if the member is not part of the aggregation level or if it is not defined correctly in the InfoObject.
  Aggregation Level: The aggregation level may not be set up to allow for exception aggregation for the specific member being queried.
  Data Model Issues: There may be issues with the underlying data model or the way the data is structured in HANA/BWA that prevents the aggregation from being performed.
  Query Design: The design of the query itself may not be compatible with exception aggregation, such as using certain filters or characteristics that conflict with the aggregation logic.
  
  Solution:
  
  Check Query Design: Review the query design to ensure that it is set up correctly for exception aggregation. Make sure that the characteristics and key figures used in the query are compatible with exception aggregation.
  Review Aggregation Levels: Ensure that the aggregation levels are correctly defined and that the current member is included in the aggregation context.
  Adjust Filters: If there are filters applied in the query, consider adjusting or removing them to see if that resolves the issue.
  Data Model Validation: Validate the data model in HANA/BWA to ensure that it is correctly set up for exception aggregation. This may involve checking the InfoObjects and their properties.
  Consult Documentation: Refer to SAP documentation or notes related to exception aggregation and the specific characteristics being used in the query for further guidance.
  Testing: Test the query with different members or without certain filters to identify if the issue is specific to certain data points.
