• What is the cause and solution for SAP error message BRAIN879 - No exc. aggr. in BWA for key figure &1 because it is a non-cumulative KF ?

  The SAP error message BRAIN879 indicates that there is an issue with the aggregation of a key figure in the Business Warehouse Accelerator (BWA). Specifically, the error states that there is "No exc. aggr. in BWA for key figure &1 because it is a non-cumulative KF." This means that the key figure in question is defined as non-cumulative, and therefore, it cannot be aggregated in the way that is being attempted.
  Cause:
  
  Non-Cumulative Key Figure: The key figure you are trying to aggregate is defined as non-cumulative. Non-cumulative key figures are typically used for values that do not accumulate over time, such as rates, averages, or other metrics that are not meant to be summed up.
  Aggregation Attempt: The error occurs when there is an attempt to perform an aggregation operation (like sum or average) on a non-cumulative key figure, which is not supported.
  
  Solution:
  
  Check Key Figure Definition: Review the definition of the key figure in the InfoObject. Ensure that it is correctly defined as non-cumulative if that is the intended behavior.
  Adjust Query Logic: If you need to perform an aggregation, consider changing the logic of your query or report to avoid aggregating non-cumulative key figures. You may need to use different key figures that are cumulative or adjust the way you are analyzing the data.
  Use Alternative Key Figures: If aggregation is necessary, look for alternative key figures that are cumulative and can be used in place of the non-cumulative key figure.
  Modify BEx Query: If you are using a BEx query, check the query design and ensure that you are not trying to aggregate non-cumulative key figures. You may need to adjust the query to avoid this error.
  
  Related Information:
  
  Key Figure Types: Understand the difference between cumulative and non-cumulative key figures in SAP BW. Cumulative key figures can be summed over time, while non-cumulative key figures represent values that should not be aggregated in that manner.
  SAP Documentation: Refer to SAP Help documentation for more details on key figure definitions and aggregation rules in SAP BW and BWA.
  BEx Query Designer: Familiarize yourself with the BEx Query Designer to better understand how to create queries that respect the characteristics of the key figures being used.
  
  By following these steps, you should be able to resolve the BRAIN879 error and adjust your queries or reports accordingly.
