• What is the cause and solution for SAP error message KX446 - The sign '_' causes problems during the transport of the key figure ?

  The SAP error message KX446 indicates that there is an issue with the use of the underscore character ('_') in the key figure name during the transport process. This error typically arises when the naming conventions for key figures in SAP BW (Business Warehouse) or SAP HANA are not adhered to, particularly when underscores are used in a way that is not supported.
  Cause:
  
  Naming Conventions: In SAP BW, certain characters, including underscores, may not be allowed in specific contexts or may lead to issues during transport. The underscore can cause confusion in the system, especially if it is used in a way that conflicts with the naming rules.
  Transport Issues: When transporting objects between different systems (e.g., from development to production), the presence of unsupported characters can lead to errors, as the transport mechanism may not handle them correctly.
  
  Solution:
  
  Rename Key Figure: The most straightforward solution is to rename the key figure to remove the underscore. Use a naming convention that adheres to SAP's guidelines, typically using alphanumeric characters without special characters.
  Check Naming Standards: Review the naming standards for key figures in your SAP environment. Ensure that all key figures comply with these standards before attempting to transport them.
  Test Transport: After renaming, perform a test transport to ensure that the issue is resolved and that the key figure can be transported without errors.
  Documentation: Document the changes made to the key figure names and communicate with your team to ensure consistency in naming conventions moving forward.
