• What is the cause and solution for SAP error message BRAIN047 - The cache was used despite virtual characteristics / key figures ?

  The SAP error message BRAIN047 indicates that the system is using a cache for a query that includes virtual characteristics or key figures. This can lead to unexpected results or performance issues because the cache may not reflect the most current data or the specific calculations required for virtual characteristics.
  Cause:
  
  Virtual Characteristics/Key Figures: The query includes virtual characteristics or key figures that are not stored in the database but are calculated at runtime. When the cache is used, it may not account for these calculations correctly.
  Cache Settings: The query might be configured to use caching, which can lead to the use of outdated or incorrect data when virtual characteristics are involved.
  Data Model: The underlying data model may not be optimized for the use of virtual characteristics, leading to conflicts when the cache is accessed.
  
  Solution:
  
  
  Disable Caching: If the query includes virtual characteristics or key figures, consider disabling caching for that specific query. This can be done in the query properties in the SAP BW Query Designer.
  
  Go to the query properties and set the caching option to "No Cache" or "Cache Disabled."
  
  
  
  Adjust Query Design: Review the design of the query to see if virtual characteristics can be avoided or if the query can be simplified to reduce complexity.
  
  
  Update Data: Ensure that the underlying data is up to date. If the data has changed, refreshing the cache may help, but be cautious with virtual characteristics.
  
  
  Check for Notes and Patches: Look for any SAP Notes or patches that address this specific issue. SAP frequently releases updates that may resolve known issues with caching and virtual characteristics.
  
  
  Consult Documentation: Review the SAP BW documentation for best practices regarding the use of virtual characteristics and caching. This can provide insights into how to structure queries effectively.
  
  
  Related Information:
  
  SAP BW Query Designer: Familiarize yourself with the Query Designer tool, as it allows you to configure queries, including caching settings.
  Performance Considerations: Understand the performance implications of using virtual characteristics and caching. While caching can improve performance, it may not be suitable for all scenarios, especially when real-time data is required.
  SAP Community and Forums: Engage with the SAP community or forums for additional insights and experiences from other users who may have encountered similar issues.
  
  By addressing the caching settings and understanding the implications of using virtual characteristics, you can resolve the BRAIN047 error and improve the performance and accuracy of your SAP BW queries.
