• What is the cause and solution for SAP error message RDB_REC029 - Requested key figures belong to different non-generic categories ?

  The SAP error message RDB_REC029 indicates that there is an issue with the key figures being used in a report or query. Specifically, this error occurs when the requested key figures belong to different non-generic categories, which means that they cannot be combined in the same context or report.
  Cause:
  
  Different Categories: The key figures you are trying to use belong to different non-generic categories. In SAP BW (Business Warehouse), key figures are often categorized based on their characteristics, and mixing them can lead to inconsistencies.
  Data Model Issues: There may be a problem with the data model or the way the key figures are defined in the InfoObjects or InfoProviders.
  Query Design: The query might be incorrectly designed, where key figures from different categories are being selected together.
  
  Solution:
  
  Check Key Figure Categories: Review the key figures involved in the query. Ensure that they belong to the same category. You can do this by checking the properties of the key figures in the SAP BW modeling tools.
  Modify the Query: If the key figures cannot be combined due to their categories, consider modifying the query to use only key figures from the same category.
  Create a New Key Figure: If necessary, create a new key figure that can aggregate or represent the data you need from the different categories.
  Consult Documentation: Refer to SAP documentation or help resources for more information on key figure categories and how to manage them in queries.
  Testing: After making changes, test the query to ensure that it runs without errors.
  
  Related Information:

  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP BW administrator or a technical consultant who can provide deeper insights into the data model and query design.
