• What is the cause and solution for SAP error message BRAIN877 - No exception aggregation in BWA for key figure &1 as it is a virtual KF ?

  The SAP error message BRAIN877 indicates that there is no exception aggregation available in the Business Warehouse Accelerator (BWA) for a specific key figure, which is defined as a virtual key figure (KF). This typically occurs when you are trying to perform an operation that requires exception aggregation on a virtual key figure, but the system does not support it.
  Cause:
  
  Virtual Key Figure: The key figure in question is defined as a virtual key figure, which means it is calculated at runtime rather than being stored in the database. Virtual key figures often do not support certain types of aggregations, including exception aggregation.
  Exception Aggregation Requirement: The operation you are trying to perform (e.g., reporting, querying) requires exception aggregation, which is not available for virtual key figures in BWA.
  BWA Limitations: The BWA may have limitations regarding the types of calculations and aggregations it can perform on virtual key figures.
  
  Solution:
  
  Change Key Figure Definition: If possible, consider changing the definition of the key figure from a virtual key figure to a regular key figure. This would allow the BWA to perform the necessary aggregations.
  Modify Query: If changing the key figure is not feasible, you may need to modify your query to avoid using exception aggregation for that specific key figure. This could involve changing the way you are aggregating data or using a different key figure that supports exception aggregation.
  Use a Different Approach: If the virtual key figure is essential for your reporting, consider using a different approach to achieve your reporting goals, such as pre-calculating the values in a different way or using a different data source that allows for the required aggregations.
  Consult Documentation: Review SAP documentation or consult with your SAP BW administrator to understand the limitations of virtual key figures and explore alternative solutions.
  
  Related Information:
  
  Exception Aggregation: This is a type of aggregation that allows for specific handling of certain values (e.g., maximum, minimum) while aggregating data. It is often used in scenarios where certain values need to be treated differently from others.
  Virtual Key Figures: These are key figures that are not physically stored in the database but are calculated on-the-fly based on other data. They can be useful for dynamic calculations but may have limitations in terms of performance and aggregation capabilities.
  SAP Notes and Documentation: Check for any relevant SAP Notes or documentation that may provide additional insights or updates regarding the use of virtual key figures and exception aggregation in BWA.
