• What is the cause and solution for SAP error message R9E062 - Characteristic &1 must only exist once in exception aggregation ?

  The SAP error message R9E062 indicates that a characteristic is being used multiple times in an exception aggregation, which is not allowed. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when defining queries or aggregations that involve exception aggregation.
  Cause:
  The error arises when you attempt to use a characteristic more than once in the context of exception aggregation. Exception aggregation is a method used in SAP BW to handle special cases in data aggregation, such as when certain values should be treated differently from others. Each characteristic should only be defined once in this context to avoid ambiguity in how the data is aggregated.
  Solution:
  To resolve this error, you should:
  
  
  Review the Query Definition: Check the query or aggregation definition where the error is occurring. Look for the characteristic mentioned in the error message (denoted as &1) and ensure that it is only included once in the exception aggregation settings.
  
  
  Remove Duplicate Characteristics: If you find that the characteristic is included multiple times, remove the duplicates. Ensure that each characteristic is only defined once in the exception aggregation.
  
  
  Adjust Aggregation Logic: If you need to aggregate data based on different criteria, consider restructuring your aggregation logic. You may need to create separate aggregations or use different characteristics to achieve the desired results.
  
  
  Test the Changes: After making the necessary adjustments, test the query or aggregation to ensure that it runs without errors and produces the expected results.
  
  
  Related Information:
