• What is the cause and solution for SAP error message BRAINOLAPAPI155 - Too many BW display hierarchies (only up to 10 hierarchies supported) ?

  The SAP error message BRAINOLAPAPI155 indicates that there are too many display hierarchies being used in a query or report in SAP BW (Business Warehouse). Specifically, the system supports a maximum of 10 display hierarchies, and if this limit is exceeded, the error will be triggered.
  Cause:
  The error occurs when a query or report attempts to use more than 10 display hierarchies. This can happen in scenarios where multiple characteristics are included in the query, and each characteristic has its own hierarchy. If the total number of hierarchies exceeds the limit, the system cannot process the request.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Query Design: Check the query definition in the Query Designer. Identify the characteristics that are using display hierarchies.
  
  
  Limit the Number of Hierarchies: 
  
  Remove unnecessary display hierarchies from the query. 
  Consider whether all the hierarchies are needed for the analysis. If some hierarchies are not essential, you can remove them to stay within the limit.
  
  
  
  Combine Hierarchies: If possible, combine hierarchies or use a single hierarchy that can serve multiple purposes instead of having multiple hierarchies for different characteristics.
  
  
  Use Alternative Structures: If you need to analyze data with more than 10 hierarchies, consider using alternative structures such as:
  
  Variables: Use variables to filter data instead of relying on multiple hierarchies.
  Calculated Key Figures: Create calculated key figures that can help in achieving the desired analysis without needing additional hierarchies.
  
  
  
  Test the Query: After making changes, test the query to ensure that it runs without errors and that the data returned meets your reporting needs.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any updates or patches related to this error. Sometimes, SAP releases notes that provide additional guidance or fixes for specific issues.
  Documentation: Refer to the SAP BW documentation for best practices on designing queries and managing hierarchies.
  Performance Considerations: Keep in mind that having too many hierarchies can also impact performance. Simplifying the query can lead to better performance and faster response times.
  
  By following these steps, you should be able to resolve the BRAINOLAPAPI155 error and optimize your BW queries effectively.
