• What is the cause and solution for SAP error message CNV10992260 - Mode 'Parallel selection' performed ?

  The SAP error message CNV10992260, which states "Mode 'Parallel selection' performed," typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This message indicates that the system is attempting to execute a parallel selection mode, which can lead to performance issues or conflicts if not managed properly.
  Cause:
  
  Data Volume: The error may arise when the volume of data being processed is too large for the system to handle in a single operation, prompting the system to switch to parallel processing.
  Configuration Issues: Incorrect configuration settings in the migration tool or the underlying database can lead to this error.
  Resource Limitations: Insufficient system resources (CPU, memory) can trigger this error, especially if multiple processes are trying to run simultaneously.
  Locking Conflicts: If multiple processes are trying to access the same data simultaneously, it can lead to locking issues, causing the error to appear.
  
  Solution:
  
  Adjust Parallel Processing Settings: Review and adjust the settings for parallel processing in the migration tool. You may want to limit the number of parallel processes to reduce contention.
  Increase System Resources: If possible, allocate more resources (CPU, memory) to the system to handle the data load more effectively.
  Batch Processing: Instead of processing all data at once, consider breaking it down into smaller batches to avoid overwhelming the system.
  Check for Locks: Use transaction codes like SM12 to check for any locks on the database that might be causing conflicts. Resolve any locks before re-running the migration.
  Review Logs: Check the migration logs for any additional error messages or warnings that could provide more context on the issue.
  Consult SAP Notes: Look for relevant SAP Notes or documentation that may address this specific error or provide guidance on best practices for data migration.
