  The SAP error message CNV_IUUC_REPLICATION028 typically indicates an issue with connecting to a remote system during data replication processes, often related to the SAP Landscape Transformation (SLT) replication server. This error can arise due to various reasons, including network issues, configuration problems, or authorization issues.
  Causes:
  
  Network Connectivity Issues: The SLT server may not be able to reach the remote system due to network problems, such as firewalls blocking the connection or incorrect network settings.
  Incorrect Configuration: The connection parameters (like hostname, port, etc.) for the remote system may be incorrectly configured in the SLT configuration.
  Authorization Issues: The user credentials used for the connection may not have the necessary permissions to access the remote system.
  Service Availability: The remote system may not be running or the required services (like the database or application server) may be down.
  Version Compatibility: There may be compatibility issues between the SLT version and the remote system version.
  
  Solutions:
