• What is the cause and solution for SAP error message BRF090 - Unexpected BRT call. You can now only use the BRF ?

  The SAP error message BRF090: Unexpected BRT call. You can now only use the BRF typically indicates an issue with the Business Rule Framework (BRF) in SAP. This error suggests that there is an attempt to call a Business Rule Tool (BRT) function that is no longer supported or has been deprecated in favor of the newer BRF+ framework.
  Cause:
  
  Deprecated Functionality: The error arises when a legacy BRT function is invoked, which is not compatible with the current version of SAP that uses BRF+.
  Configuration Issues: There may be configurations or custom developments that still reference the old BRT instead of the BRF+.
  System Upgrade: If the system has been upgraded from an older version of SAP to a newer one, some components may still be using the old BRT calls.
  
  Solution:
  
  
  Update Code: Review the code or configuration that is triggering the error and update it to use BRF+ instead of BRT. This may involve:
  
  Replacing BRT function calls with their BRF+ equivalents.
  Modifying any custom logic that relies on BRT.
  
  
  
  Check Custom Developments: If there are custom developments or enhancements, ensure they are updated to comply with BRF+ standards.
  
  
  Review BRF+ Configuration: Ensure that the BRF+ configuration is correctly set up and that all necessary rules and decision tables are defined.
  
  
  Consult Documentation: Refer to SAP documentation for BRF+ to understand the differences and how to migrate from BRT to BRF+.
  
  
  Testing: After making changes, thoroughly test the application to ensure that the new BRF+ logic works as intended and that the error does not recur.
