• What is the cause and solution for SAP error message BRAIN162 - &1 cannot be input. &2 has aggregation &3. ?

  The SAP error message BRAIN162 typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there is an issue with the aggregation of data in a query or report. The message indicates that a certain characteristic (denoted as &1) cannot be input because it has an aggregation defined (denoted as &3) for another characteristic (denoted as &2).
  Cause:
  
  Aggregation Conflict: The error arises when you try to input a characteristic that is not compatible with the aggregation settings of another characteristic in the query. For example, if you have a characteristic that is aggregated at a higher level, you cannot input a lower-level characteristic directly.
  Query Design: The design of the query may not allow for certain combinations of characteristics due to the way aggregations are set up.
  Data Model Issues: There may be issues with the underlying data model or InfoProvider that prevent the input of certain characteristics.
  
  Solution:
  
  Review Query Design: Check the query design in the BEx Query Designer. Ensure that the characteristics and their aggregations are set up correctly. You may need to adjust the aggregation settings or the characteristics used in the query.
  Adjust Aggregation Levels: If possible, modify the aggregation levels of the characteristics involved to allow for the desired input. This may involve changing the aggregation settings in the InfoObject or the query.
  Use Filters: Instead of trying to input the characteristic directly, consider using filters or variables that allow for the selection of the desired data without conflicting with the aggregation.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling aggregation issues in your version of SAP BW/BI.
  Testing: After making changes, test the query to ensure that the error is resolved and that the data is being aggregated and displayed as expected.
