  The SAP error message "CNV_PE854 RFC settings are not unique in project &1" typically occurs during the execution of a project that involves data migration or conversion, particularly when using the SAP Landscape Transformation (SLT) or SAP Data Services tools. This error indicates that there are multiple RFC (Remote Function Call) destinations configured for the same project, which can lead to ambiguity in the system regarding which RFC destination to use.
  Cause:
  
  Duplicate RFC Destinations: The error is primarily caused by having multiple RFC destinations defined for the same project. This can happen if the configuration was not done correctly or if there were changes made to the RFC settings that were not properly updated in the project.

  Project Misconfiguration: The project might have been set up in a way that does not clearly define which RFC destination should be used for specific operations.
  
  Solution:
  
  Check RFC Destinations: Go to transaction SM59 in the SAP GUI and check the RFC destinations configured for the project. Look for duplicates or inconsistencies.
  Remove Duplicates: If you find multiple RFC destinations for the same project, you will need to remove or consolidate them to ensure that there is only one unique RFC destination for the project.
  Update Project Settings: Ensure that the project settings are correctly pointing to the intended RFC destination. This may involve updating the project configuration in the relevant transaction or tool.
  Test RFC Connections: After making changes, test the RFC connections to ensure they are functioning correctly and that the project can access the necessary resources.
  Consult Documentation: Refer to the SAP documentation or notes related to the specific data migration or conversion tool you are using for any additional configuration steps or best practices.
