• What is the cause and solution for SAP error message CNV_IUUC_REPL_TS051 - Connection &1 to target system is not active (MT ID &2) ?

  The SAP error message CNV_IUUC_REPL_TS051 indicates that there is an issue with the connection to the target system during a data replication process. This error typically arises in the context of SAP Landscape Transformation (SLT) or data replication scenarios where the source system is trying to connect to a target system, but the connection is not active.
  Cause:
  
  Inactive Connection: The target system connection might not be active or properly configured in the SAP system.
  Network Issues: There could be network connectivity issues between the source and target systems.
  Authorization Issues: The user credentials used for the connection may not have the necessary authorizations.
  Configuration Errors: There may be misconfigurations in the SLT configuration or in the RFC destination settings.
  Target System Down: The target system might be down or not reachable.
  
  Solution:
  
  
  Check Connection Status:
  
  Go to transaction SM59 in the source system and check the RFC destination that points to the target system. Ensure that the connection is active and test the connection to verify it works.
  
  
  
  Network Connectivity:
  
  Ensure that there are no network issues preventing the source system from reaching the target system. You can use tools like ping or traceroute to check connectivity.
  
  
  
  User Authorizations:
  
  Verify that the user credentials used for the connection have the necessary authorizations in both the source and target systems.
  
  
  
  Review SLT Configuration:
  
  Check the SLT configuration in transaction LTRC to ensure that the target system is correctly configured and that the replication settings are correct.
  
  
  
  Check Target System Status:
  
  Ensure that the target system is up and running. If it is down, you will need to bring it back online.
  
  
  
  Logs and Traces:
  
  Review the logs in the SLT system for any additional error messages that might provide more context about the issue. You can check the logs in transaction SLG1.
  
  
  
  Restart Replication:
  
  If the connection was previously inactive but has been fixed, you may need to restart the replication process to establish the connection again.
