What causes this issue?

Batch <LS>&V1&</> of material <LS>&V2&</> is currently locked in plant
<LS>&V3&</> and cannot be edited. The lock was set during editing of
another batch of material <LS>&V2&</> to ensure that the batches of
this material are classified consistently.
In plant <LS>&V3&</>, there are various classified batches for material
<LS>&V2&</>, which is not classified. At least one of the batches of
material <LS>&V2&</> is being edited in a parallel session, whereby the
system set a lock for batch <LS>&V1&</> in plant <LS>&V3&</>. This lock
should prevent different classes from being assigned to these batches
as a result of simultaneous editing of batches of material <LS>&V2&</>
in various sessions.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Finish editing all batches of material <LS>&V1&</> in parallel
sessions.

• What is the cause and solution for SAP error message 12189 - Batch &1 of material &2 is locked by user &4 in plant &3 ?

  The SAP error message 12189 indicates that a specific batch of a material is locked by another user in a particular plant. This typically occurs when a user is performing an operation that requires exclusive access to the batch, such as during inventory management, production planning, or quality management processes.
  Cause:
  
  User Lock: Another user is currently working with the same batch, which prevents other users from making changes or performing certain actions on that batch.
  Transaction in Progress: A transaction that involves the batch is still in progress, and the system locks the batch to ensure data integrity.
  Batch Management Settings: The system may be configured to lock batches during specific operations to prevent concurrent modifications.
  
  Solution:
  
  Identify the Locking User: Check who is currently using the batch. You can use transaction code SM12 to view the locks in the system. Look for the user ID mentioned in the error message.
  Wait for Release: If the locking user is performing a legitimate operation, you may need to wait until they complete their task and release the lock.
  Contact the User: If you know the user who is locking the batch, you can contact them to see if they can complete their task or release the lock.
  Force Release (if necessary): If the locking session is no longer active (e.g., the user has logged off unexpectedly), a system administrator can manually delete the lock using transaction code SM12. However, this should be done with caution to avoid data inconsistencies.
  Review Batch Management Settings: If this issue occurs frequently, consider reviewing the batch management settings and processes to minimize locking conflicts.
