• What is the cause and solution for SAP error message IUUC_MOD035 - Could not retrieve target connection info ?

  The SAP error message IUUC_MOD035, which states "Could not retrieve target connection info," typically occurs in the context of SAP Landscape Transformation (SLT) or Data Replication processes. This error indicates that the system is unable to access or retrieve the necessary connection information for the target system where data is supposed to be replicated.
  Causes:
  
  Connection Configuration Issues: The target connection may not be properly configured in the SLT system. This could be due to incorrect parameters or missing entries in the configuration.
  Network Issues: There may be network connectivity problems between the source and target systems, preventing the SLT system from accessing the target.
  Authorization Issues: The user credentials used for the connection may not have the necessary authorizations to access the target system.
  Target System Down: The target system may be down or not reachable at the time of the data replication process.
  Incorrect RFC Destination: The Remote Function Call (RFC) destination for the target system may be incorrectly set up or not functioning.
  
  Solutions:
  
  
  Check Connection Configuration:
  
  Verify the configuration of the target connection in the SLT system. Ensure that all parameters (like hostname, system number, client, user, and password) are correctly set.
  Use transaction SM59 to check the RFC destination for the target system. Test the connection to ensure it is working.
  
  
  
  Network Connectivity:
  
  Ensure that there are no network issues between the SLT system and the target system. You can use tools like ping or telnet to check connectivity.
  
  
  
  Authorization Check:
  
  Verify that the user credentials used for the connection have the necessary authorizations in the target system. This includes permissions to write data and access the relevant tables.
  
  
  
  Check Target System Status:
  
  Ensure that the target system is up and running. Check for any maintenance activities or downtimes that might affect connectivity.
  
  
  
  Review Logs:
  
  Check the SLT logs for more detailed error messages. You can find logs in transaction SLG1 (Application Log) and look for messages related to the replication process.
  
  
  
  Restart Replication:
  
  If the issue persists, consider stopping and restarting the replication process to see if it resolves the issue.
