This error typically arises during data migration or conversion processes in SAP systems, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.

  Solution:
  To resolve this error, you can follow these steps:

  Ensure that the destination is correctly configured and that it points to the appropriate system.
  
  
  
  Create or Update Trusted RFC Connection:

  If it exists but is not functioning, consider updating the connection settings or recreating it.
  
  
  
  Check User Authorizations:
  
  Ensure that the user executing the CDMC activities has the necessary authorizations to access the TMW destination.
  You may need to check roles and profiles assigned to the user.
  
  
  
  Verify Trust Relationship:
