• What is the cause and solution for SAP error message BRAIN872 - No exception aggr. in BWA for key figure &1 because of tempo. hier. join ?

  The SAP error message BRAIN872 indicates that there is no exception aggregation available in the Business Warehouse Accelerator (BWA) for a specific key figure due to a temporary hierarchy join. This error typically arises in the context of reporting or querying in SAP BW when the system is unable to perform the required aggregation due to the way the data is structured or the specific settings of the query.
  Cause:
  
  Temporary Hierarchy Join: The error suggests that the key figure you are trying to aggregate is linked to a temporary hierarchy that does not support exception aggregation. Temporary hierarchies are often used for specific reporting scenarios but may not be compatible with certain types of aggregations.
  Key Figure Settings: The key figure may not be set up to allow for exception aggregation, or the settings may not be correctly configured in the InfoObject.
  Data Model Issues: There may be issues with the underlying data model or the way the data is being joined, which can lead to the inability to perform the required aggregation.
  
  Solution:
  
  Check Hierarchy Settings: Review the settings of the temporary hierarchy being used. Ensure that it is correctly defined and that it supports the type of aggregation you are trying to perform.
  Modify Query: If possible, modify the query to avoid using the temporary hierarchy or to use a different key figure that does support exception aggregation.
  Key Figure Configuration: Check the configuration of the key figure in the InfoObject. Ensure that it is set up to allow for exception aggregation if that is required for your reporting needs.
  Data Model Review: Review the data model and the joins being used. Ensure that the joins are correctly defined and that they do not lead to situations where aggregation cannot be performed.
  Consult Documentation: Refer to SAP documentation or notes related to BWA and exception aggregation for any specific guidelines or updates that may apply to your version of SAP BW.
