• What is the cause and solution for SAP error message BRAIN868 - Exception aggregation for constant &1 will be performed in BWA/HANA ?

  The SAP error message BRAIN868 indicates that there is an issue with the aggregation of a constant in the context of SAP BW (Business Warehouse) or HANA. This message typically arises when the system is unable to perform the expected aggregation due to the nature of the constant being used in a query or calculation.
  Cause:
  
  Constant Aggregation: The error suggests that the system is trying to aggregate a constant value, which may not be supported in the way the query is structured. This can happen if the constant is not properly defined or if the aggregation logic does not align with the expected behavior of the system.
  Query Design: The design of the query may be such that it does not allow for proper aggregation of the constant, leading to the exception.
  Data Model Issues: There may be issues with the underlying data model or InfoProvider that prevent the aggregation from being performed correctly.
  
  Solution:
  
  Review Query Design: Check the query design in the BEx Query Designer. Ensure that the constants are defined correctly and that the aggregation logic is appropriate for the data being queried.
  Modify Aggregation Logic: If possible, modify the aggregation logic to avoid using constants in a way that leads to this error. Consider using variables or other dynamic elements instead of hard-coded constants.
  Check Data Model: Review the underlying data model and InfoProviders to ensure that they are set up correctly and that there are no inconsistencies that could lead to aggregation issues.
  Update SAP Notes: Check for any relevant SAP Notes or updates that may address this specific error. Sometimes, SAP releases patches or notes that provide fixes or workarounds for known issues.
