• What is the cause and solution for SAP error message RSRTS_CDS084 - Identifier &1 (exception aggregation of pos &2) is not a characteristic ?

  The SAP error message RSRTS_CDS084 typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when working with Composite Data Sources (CDS) views or queries. This error indicates that there is an issue with the aggregation of a characteristic in a query or a data model.
  Cause:
  The error message "Identifier &1 (exception aggregation of pos &2) is not a characteristic" usually arises due to one of the following reasons:
  
  
  Incorrect Aggregation: The identifier specified in the error message is not recognized as a characteristic in the context of the query or data model. This can happen if the identifier is mistakenly used in an aggregation context where a characteristic is expected.
  
  
  Modeling Issues: There may be a problem with the way the data model is defined. For example, if a measure is being treated as a characteristic or if there are inconsistencies in the data model.
  
  
  Query Design: The query might be incorrectly designed, where a non-characteristic field is being used in a place where a characteristic is required, such as in exception aggregation.
  
  
  Data Source Issues: The underlying data source may not be properly defined or may not contain the expected characteristics.
  
  
  Solution:
  To resolve the RSRTS_CDS084 error, you can take the following steps:
  
  
  Check Query Design:
  
  Review the query definition in the Query Designer. Ensure that all fields used in the aggregation are correctly defined as characteristics or measures.
  Make sure that the identifiers used in the exception aggregation are valid characteristics.
  
  
  
  Review Data Model:
  
  Check the underlying data model (e.g., InfoObjects, Composite Providers) to ensure that the identifiers are correctly defined and that they are indeed characteristics.
  Validate that the data source used in the query contains the expected fields.
  
  
  
  Adjust Aggregation Logic:
  
  If you are using exception aggregation, ensure that the logic is correctly applied to the appropriate characteristics. You may need to adjust the aggregation settings in the query.
  
  
  
  Test with Simplified Query:
  
  If the issue persists, try creating a simplified version of the query to isolate the problem. Start with a basic query and gradually add complexity to identify the specific cause of the error.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or community forums for additional insights on the specific error message and potential fixes.
