What causes this issue?

A requested lock on table &V1& cannot be guaranteed because the lock is
already held by an SAP transaction of user &V2&.

System Response

The data of table &V1& could not be deleted.
If this message occurs in the preprocessing program for archiving object

If this error occurs elsewhere, the message is for information. The
system deletes the data from table &V1& the next time the preprocessing
program is started. If you want to empty table &V1& before this, use
report <AB>AUT_ARCH_UNDO</> once the current lock has been released.

How to fix this error?

Look in the lock table to see which user or transaction is holding the
requested lock (Tools -> Administration ==> Monitor -> Lock Entries). If
necessary, contact this user.

Procedure for System Administrators

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

• What is the cause and solution for SAP error message AUT126 - Table &1 is currently locked by user &2 ?

  The SAP error message AUT126 indicates that a specific table (denoted as &1) is currently locked by a user (denoted as &2). This typically occurs when a user or a process is accessing or modifying the table, preventing other users from performing operations on it until the lock is released.
  Cause:
  
  User Lock: A user is currently editing or has an open session that is locking the table.
  Long-Running Transactions: A transaction that takes a long time to complete may hold a lock on the table.
  Uncommitted Changes: If a user has made changes to the table but has not yet committed those changes, the table remains locked.
  Deadlocks: In some cases, a deadlock situation may arise where two or more processes are waiting for each other to release locks.
  
  Solution:
  
  Identify the Locking User: Use transaction code SM12 to view the list of locks. You can filter by the table name and the user to identify who is holding the lock.
  Communicate with the User: If possible, contact the user who is holding the lock to determine if they can release it by completing or rolling back their transaction.
  Release the Lock: If the user is unavailable or the session is no longer active, an administrator can manually delete the lock entry in SM12. However, this should be done with caution, as it may lead to data inconsistency if the user is in the middle of a transaction.
  Check for Long-Running Transactions: Use transaction SM66 to monitor active processes and identify any long-running transactions that may be causing locks.
  Review Application Logic: If this issue occurs frequently, review the application logic to ensure that locks are being managed properly and that transactions are being committed or rolled back in a timely manner.
