• What is the cause and solution for SAP error message CNV453 - Phase cannot be activated due to active packages in other client ?

  The SAP error message CNV453 indicates that a phase in a conversion or migration process cannot be activated because there are active packages in another client. This typically occurs during data migration or system conversion processes, such as when using the SAP S/4HANA Migration Cockpit or other tools that involve client-specific activities.
  Cause:
  The error is caused by the presence of active packages in a different client that are preventing the current phase from being activated. This can happen if:
  
  There are ongoing processes or transactions in another client that are locking resources.
  The system is configured in a way that requires certain conditions to be met before proceeding with the phase activation.
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check Active Packages:
  
  Identify which packages are active in the other client. You can do this by checking the transaction logs or using transaction codes like SE09 or SE10 to view transport requests.
  
  
  
  Deactivate or Complete Processes:
  
  If possible, deactivate or complete the processes that are using the active packages in the other client. This may involve coordinating with other teams or users who are working in that client.
  
  
  
  Switch Clients:
  
  If you have access to the other client, you can switch to that client and either complete or release the active packages.
  
  
  
  Transport Requests:
  
  If the active packages are related to transport requests, ensure that they are either released or imported into the target client.
  
  
  
  Check for Locks:
  
  Use transaction SM12 to check for any locks that might be preventing the phase from being activated. If there are locks that are no longer needed, you can delete them.
  
  
  
  Retry Activation:
  
  Once the active packages are resolved, retry activating the phase in the original client.
