• What is the cause and solution for SAP error message BRAIN_DEV138 - &1: exception aggregation ref. characteristic is compounded ?

  The SAP error message BRAIN_DEV138 indicates that there is an issue with the aggregation of a reference characteristic that is compounded in a query or report. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when working with InfoProviders, queries, or data models that involve compounded characteristics.
  Cause:
  The error arises when:
  
  A reference characteristic that is compounded (i.e., it is based on multiple characteristics) is being used in a way that is not supported for aggregation.
  The query or report is trying to aggregate data based on a compounded characteristic, which can lead to ambiguity in how the data should be summarized.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Query Design:
  
  Review the query or report where the error occurs. Ensure that you are not trying to aggregate data based on a compounded characteristic directly.
  If you need to use the compounded characteristic, consider using the individual characteristics that make up the compound instead.
  
  
  
  Modify the InfoProvider:
  
  If you have control over the InfoProvider, consider redesigning it to avoid using compounded characteristics for aggregation purposes.
  You may need to create a new InfoObject that is not compounded or adjust the existing compounded characteristic to better suit your reporting needs.
  
  
  
  Adjust Aggregation Settings:
  
  In some cases, you may need to adjust the aggregation settings in the query designer. Ensure that the aggregation behavior is appropriate for the characteristics being used.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on handling compounded characteristics in queries and reports.
  
  
  
  Testing:
  
  After making changes, test the query or report to ensure that the error is resolved and that the data is being aggregated correctly.
