• What is the cause and solution for SAP error message CNV_MBT096 - Locking users .... ?

  The SAP error message CNV_MBT096 typically relates to issues with locking users during a data migration or conversion process, often associated with the SAP S/4HANA migration or other data transfer activities. This error can occur when the system attempts to lock users for data consistency but encounters issues, such as users being logged in or other processes accessing the same data.
  Cause:
  
  Active User Sessions: The users that the system is trying to lock are currently logged in and performing actions, which prevents the system from locking them.
  Background Jobs: There may be background jobs or processes that are accessing the same data, leading to conflicts.
  Insufficient Authorizations: The user executing the migration may not have the necessary authorizations to lock other users.
  System Configuration: There may be configuration settings that prevent user locking or that are not set up correctly.
  
  Solution:
  
  Log Out Users: Ensure that all users who need to be locked are logged out of the system. You can use transaction code SM04 to monitor active user sessions and log them out if necessary.
  Check Background Jobs: Review any background jobs that may be running and accessing the same data. You can use transaction code SM37 to check for active jobs and terminate them if needed.
  Run in Maintenance Mode: If possible, run the migration or conversion process during a maintenance window when user activity is minimal.
  Review Authorizations: Ensure that the user executing the migration has the necessary authorizations to lock users. This may involve checking roles and permissions.
  System Configuration: Review the system configuration related to user locking and ensure it is set up correctly.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM04 (User Overview), SM37 (Job Monitoring), and SU01 (User Maintenance) for managing user sessions and authorizations.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
