• What is the cause and solution for SAP error message USMD2122 - A maximum of 999 rows can be inserted at one time ?

  The SAP error message USMD2122 indicates that you are trying to insert more than the allowed maximum of 999 rows in a single operation. This limitation is often encountered when working with data migration or mass data uploads in SAP systems, particularly in the context of SAP Master Data Governance (MDG) or similar data management scenarios.
  Cause:
  The error occurs because the system has a built-in restriction on the number of rows that can be processed in a single transaction. This is a safeguard to ensure system performance and stability, as processing too many rows at once can lead to performance degradation or even system crashes.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Batch Processing: Instead of trying to insert all rows at once, break your data into smaller batches of 999 rows or fewer. You can implement a loop in your data upload script or program to handle multiple batches sequentially.
  
  
  Data Upload Tools: If you are using tools like LSMW (Legacy System Migration Workbench), BAPIs, or other data upload methods, ensure that you configure them to handle batch processing. Many tools have options to specify batch sizes.
  
  
  Check Configuration: If you are using custom programs or scripts, review the code to ensure it adheres to the row limit. Modify the logic to process data in smaller chunks.
  
  
  Error Handling: Implement error handling in your data upload process to catch and log errors for each batch, allowing you to troubleshoot issues without losing all progress.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific transaction or tool you are using for any additional guidance on handling large data sets.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional context or updates regarding this error message.
  Performance Considerations: When working with large datasets, consider the overall performance of your SAP system. Monitor system resources and performance metrics during data uploads.
  Testing: Always test your data upload process in a development or quality assurance environment before executing it in production to ensure that it works as expected without hitting system limits.
  
  By following these steps, you should be able to effectively manage the data insertion process and avoid the USMD2122 error.
