  The SAP error message CNV_LTHCM_G_30003 indicates a system failure when calling a function module (FM) with a specific destination. This error is often related to issues in the data migration process, particularly in the context of the SAP Landscape Transformation (SLT) or data conversion scenarios.
  Cause:
  
  Function Module Issues: The function module specified in the error message may not be available, may have been deleted, or may not be properly activated.
  Destination Configuration: The destination specified in the error message may not be correctly configured in the SAP system. This could include issues with RFC (Remote Function Call) destinations.
  Authorization Issues: The user executing the function may not have the necessary authorizations to call the function module.
  System Resource Issues: There may be resource constraints on the system, such as memory or processing power, leading to a failure in executing the function.
  Network Issues: If the function module is trying to access a remote system, network issues could prevent successful communication.
  
  Solution:
  
  Check Function Module: Verify that the function module specified in the error message exists and is active. You can do this by using transaction SE37 (Function Builder) to check the status of the function module.
  Review Destination Configuration: Use transaction SM59 to check the configuration of the RFC destination mentioned in the error message. Ensure that it is correctly set up and that the connection is working.
  Check Authorizations: Ensure that the user has the necessary authorizations to execute the function module. You can check this using transaction SU53 to analyze authorization failures.
  Monitor System Resources: Check system logs and performance metrics to identify any resource constraints. You can use transaction ST22 for dumps and SM21 for system logs.
  Network Connectivity: If the function module is calling a remote system, ensure that there are no network issues preventing communication. You can use tools like ping or telnet to test connectivity.
  Debugging: If the issue persists, consider debugging the function module to identify the exact point of failure. You can set breakpoints in the function module code to analyze the execution flow.
