  The SAP error message /EACC/DM_QUERY021 Exception aggregation: Non-permitted selection condition for ref. fld &1 typically occurs in the context of SAP Analytics Cloud (SAC) or SAP BW (Business Warehouse) when working with exception aggregation in queries. This error indicates that there is a problem with the selection conditions applied to a reference field in the context of exception aggregation.
  Cause:
  
  
  Invalid Selection Condition: The error is triggered when a selection condition is applied to a reference field that is not allowed in the context of exception aggregation. This can happen if the reference field is not part of the aggregation logic or if the selection condition contradicts the aggregation rules.
  
  
  Aggregation Logic: The aggregation logic defined in the query may not support the selection condition applied to the reference field. For example, if the reference field is meant to be aggregated in a certain way, applying a filter that contradicts this logic can lead to this error.

  Solution:

  Adjust Aggregation Logic: If necessary, modify the aggregation logic in your query to accommodate the selection conditions. This may involve changing how the reference field is aggregated or removing conflicting conditions.
  
  
  Field Configuration: Verify the configuration of the reference field in the data model. Ensure that it is set up correctly for use with exception aggregation and that its properties align with the intended use in the query.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on exception aggregation and the specific requirements for reference fields. This can provide insights into best practices and common pitfalls.
