• What is the cause and solution for SAP error message CNV_LTHCM_A_10019 - Maximum number of table changes reached; please restart program ?

  The SAP error message CNV_LTHCM_A_10019 indicates that the maximum number of table changes has been reached during a data migration or conversion process, specifically in the context of the SAP Landscape Transformation (SLT) or similar data migration tools. This error typically occurs when the program is processing a large volume of data and exceeds the predefined limits for changes to database tables in a single run.
  Cause:
  
  Exceeding Limits: The program has a limit on the number of changes (inserts, updates, deletes) it can handle in one execution cycle. When this limit is reached, the program cannot process any further changes until it is restarted.
  Large Data Volume: If you are migrating or transforming a large dataset, it is possible to hit this limit quickly.
  Configuration Settings: The maximum number of changes allowed may be set too low in the configuration of the migration program.
  
  Solution:
  
  Restart the Program: The immediate solution is to restart the program as suggested by the error message. This will clear the current state and allow the program to start processing again.
  Increase Limits: If this error occurs frequently, consider increasing the maximum number of changes allowed. This can usually be done in the configuration settings of the migration tool. Check the relevant parameters in the program or transaction codes related to the data migration.
  Batch Processing: If you are processing a very large dataset, consider breaking it down into smaller batches. This can help avoid hitting the limit in a single run.
  Monitor Performance: Keep an eye on the performance and resource usage of the system during the migration process. If the system is under heavy load, it may be beneficial to schedule the migration during off-peak hours.
  Consult Documentation: Refer to the official SAP documentation or notes related to the specific migration tool you are using for any additional configuration options or best practices.
  
  Related Information:
  
  Transaction Codes: Depending on the specific migration tool, you may need to use specific transaction codes to adjust settings or monitor the migration process.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or patches related to this error.
  Logs and Traces: Review the logs generated by the migration program for any additional error messages or warnings that could provide more context on the issue.
  
  If the problem persists after trying the above solutions, it may be beneficial to reach out to SAP support or consult with a technical expert familiar with the specific migration tool you are using.
