• What is the cause and solution for SAP error message BRAIN874 - No exception aggregation in BWA for &1 because of virtual characteristics ?

  The SAP error message BRAIN874 indicates that there is an issue with exception aggregation in the Business Warehouse Accelerator (BWA) due to the presence of virtual characteristics in your query. This error typically arises when you are trying to perform exception aggregation on a characteristic that is defined as virtual in the context of your BEx query.
  Cause:
  
  Virtual Characteristics: The error occurs because the query includes virtual characteristics, which are not physically stored in the data model but are derived at runtime. Exception aggregation cannot be performed on these characteristics since they do not have a direct mapping to the underlying data.
  Query Design: The design of the query may include characteristics that are not suitable for exception aggregation, leading to this error.
  
  Solution:
  To resolve the BRAIN874 error, you can consider the following approaches:
  
  
  Remove Virtual Characteristics: If possible, modify your query to exclude virtual characteristics. This may involve redesigning the query to use only physical characteristics that can support exception aggregation.
  
  
  Adjust Exception Aggregation: Review the exception aggregation settings in your query. Ensure that the characteristics used for exception aggregation are physical and not virtual.
  
  
  Check Query Properties: Go to the properties of the query in the BEx Query Designer and check the settings related to exception aggregation. Make sure that the characteristics involved in the exception aggregation are appropriate.
  
  
  Use Alternative Aggregation Methods: If you need to keep the virtual characteristics, consider using alternative aggregation methods that do not rely on exception aggregation.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on handling virtual characteristics and exception aggregation.
