  The SAP error message RSR_EXPLAIN017 indicates that there is an issue with the execution of a formula variable in a query that is being processed in SAP BW (Business Warehouse) on HANA or BWA (Business Warehouse Accelerator). The specific message states that there is "No exception aggregation in HANA/BWA for formula variable &1 due to formula exception aggregation."
  Cause:
  This error typically arises when:
  
  Formula Variables: The formula variable you are trying to use in your query is defined with exception aggregation, but the underlying HANA or BWA system does not support this type of aggregation for the specific formula.
  Incompatibility: The formula may be using functions or operations that are not compatible with the HANA or BWA engine, which can lead to the inability to perform the required calculations.
  Data Model: The data model or the way the InfoProvider is set up may not support the required exception aggregation for the formula variable.
  
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check Formula Definition: Review the definition of the formula variable in the query. Ensure that it is correctly defined and that the exception aggregation is necessary for your use case.
  
  
  Modify Exception Aggregation: If possible, modify the formula to avoid using exception aggregation. This may involve changing the logic of the formula or using standard aggregation methods that are supported by HANA/BWA.
  
  
  Use Alternative Calculations: If the formula cannot be changed, consider using alternative calculations or approaches that do not rely on exception aggregation.
  
  
  Update Query Design: If the query design allows, try to redesign the query to avoid the use of the problematic formula variable or to use a different InfoProvider that supports the required calculations.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to your specific version of BW on HANA/BWA for any known limitations or additional guidance on handling formula variables.
  
  
  Testing: After making changes, test the query to ensure that it runs without errors and produces the expected results.
