• What is the cause and solution for SAP error message CNV_MBT084 - Users successfully locked in the system. ?

  The SAP error message CNV_MBT084 indicates that users are successfully locked in the system, which typically occurs during a data migration or conversion process. This message is part of the SAP Conversion and Migration tools, particularly in the context of the SAP S/4HANA migration.
  Cause:
  The error usually arises when:
  
  User Locking Mechanism: The system has a mechanism to lock users to prevent changes during critical operations like data migration. If users are locked, it may indicate that the migration process is trying to access or modify data that is currently being used or modified by those users.
  Concurrent Sessions: Multiple users may be logged into the system, and the migration process is trying to perform actions that require exclusive access to certain data or transactions.
  Configuration Issues: There may be configuration settings that dictate how user locks are handled during migration processes.
  
  Solution:
  To resolve the CNV_MBT084 error, consider the following steps:
  
  
  Identify Locked Users: Check which users are locked in the system. You can do this by using transaction code SU01 or SU10 to view user statuses.
  
  
  Unlock Users: If possible, unlock the users who are currently locked. This can be done by an administrator using the same transaction codes mentioned above. Ensure that unlocking users does not disrupt ongoing business processes.
  
  
  Schedule Downtime: If the migration process requires exclusive access to the system, consider scheduling a downtime period where no users are allowed to log in. This will prevent any locking issues during the migration.
  
  
  Review Migration Settings: Check the settings and configurations of the migration tool you are using. Ensure that it is set up correctly to handle user locks and that it is not trying to access data that is currently in use.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using. There may be specific guidelines or best practices for handling user locks during migration.
  
  
  Contact SAP Support: If the issue persists, consider reaching out to SAP Support for assistance. They may provide insights specific to your system configuration and the migration process you are undertaking.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SU01 (User Maintenance), SU10 (Mass User Maintenance), and SM12 (Lock Entries) to manage user locks effectively.
  Migration Tools: Understand the specific migration tools you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) and their requirements regarding user access and locks.
  Best Practices: Follow best practices for data migration, including proper planning, user communication, and system monitoring to minimize disruptions.
  
  By following these steps, you should be able to address the CNV_MBT084 error and proceed with your migration or conversion process smoothly.
