• What is the cause and solution for SAP error message IUUC_CLOG_CORE357 - Alternative RFC Source Connection for Initial Load ?

  The SAP error message "IUUC_CLOG_CORE357 Alternative RFC Source Connection for Initial Load" typically occurs in the context of SAP Landscape Transformation (SLT) replication setups. This error indicates that there is an issue with the RFC (Remote Function Call) connection used for the initial data load from the source system to the target system.
  Cause:
  
  
  RFC Connection Issues: The primary cause of this error is often related to the RFC connection settings. This could be due to:
  
  Incorrect configuration of the RFC destination in the SAP system.
  Network issues preventing the connection to the source system.
  The source system being down or unreachable.
  Authorization issues where the user does not have the necessary permissions to access the source system.
  
  
  
  Configuration Errors: There may be misconfigurations in the SLT setup, such as incorrect source system settings or parameters.
  
  
  Performance Issues: If the source system is under heavy load, it may not be able to handle the initial load request, leading to connection failures.
  
  
  Solution:
  
  
  Check RFC Connection:
  
  Go to transaction SM59 in the SAP GUI and verify the RFC destination settings for the source system.
  Test the connection to ensure it is working properly. If there are issues, correct the settings or resolve any network problems.
  
  
  
  Review SLT Configuration:
  
  Ensure that the SLT configuration is correct. Check the settings in transaction LTRC (SLT Configuration) and ensure that the source system is properly defined.
  Verify that the necessary parameters for the initial load are set correctly.
  
  
  
  Authorization Check:
  
  Ensure that the user used for the RFC connection has the necessary authorizations to access the source system and perform the initial load.
  
  
  
  Monitor System Performance:
  
  Check the performance of the source system. If it is under heavy load, consider scheduling the initial load during off-peak hours or optimizing the source system's performance.
  
  
  
  Logs and Traces:
  
  Review the SLT logs and traces for more detailed error messages. You can find logs in transaction LTRC or SLG1 for application logs related to SLT.
  
  
  
  Alternative RFC Source Connection:
  
  If the primary RFC connection continues to fail, consider configuring an alternative RFC connection in the SLT settings. This can be done in the SLT configuration where you can specify multiple RFC destinations.
