• What is the cause and solution for SAP error message UCFE015 - Only one hierarchy is allowed in a row structure ?

  The SAP error message UCFE015, which states "Only one hierarchy is allowed in a row structure," typically occurs in the context of SAP BW (Business Warehouse) or SAP BPC (Business Planning and Consolidation) when you are trying to create or modify a report or query that involves hierarchies.
  Cause:
  This error arises when you attempt to include multiple hierarchies in a single row structure of a report or query. In SAP BW/BPC, a row structure can only accommodate one hierarchy at a time. This limitation is in place to ensure that the data is presented in a clear and unambiguous manner.
  Solution:
  To resolve the UCFE015 error, you can take the following steps:
  
  
  Review the Query/Report Design: Check the design of your query or report. Ensure that you are not trying to include more than one hierarchy in the row structure.
  
  
  Modify the Row Structure:
  
  If you need to display multiple hierarchies, consider restructuring your report. You can create separate rows for each hierarchy or use different sections of the report to display them.
  Alternatively, you can use a different layout or format that allows for the inclusion of multiple hierarchies, such as using columns instead of rows.
  
  
  
  Use Variables or Filters: If applicable, use variables or filters to allow users to select which hierarchy they want to view, rather than trying to display them simultaneously.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources for specific guidelines on how to structure your queries and reports to avoid this error.
  
  
  Testing: After making the necessary adjustments, test the report or query to ensure that it runs without errors and displays the desired data.

  By following these steps, you should be able to resolve the UCFE015 error and successfully create your report or query in SAP.
