What causes this issue?

A requested lock on table &V1& cannot be granted because an SAP
transaction of user &V2& already holds the lock in question.

System Response

The data of table &V1& cannot be deleted.
If this message is issued within the framework of the preprocessing
program for archiving object SELR_LTXTS, the system terminates the
processing.
If this message is issued outside the preprocessing program, it serves
for information only. The system will delete the data from table &V1&
when the preprocessing program is next started. If you wish to empty
table &V1& before this, use report SAUT_ARCH_UNDO<(>,<)> <AB></> for
this purpose after the current lock has been released.

How to fix this error?

Look in the lock table to see which user or which transaction holds the
requested lock (<LS>Tools -> Administration -> Monitor -> Lock Entries
</>). Contact the relevant user if necessary.

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 S_AUT126 - Table &1 currently locked by user &2 ?

  The SAP error message S_AUT126 indicates that a specific table (denoted as &1) is currently locked by a user (denoted as &2). This typically occurs when a user is performing an operation that requires exclusive access to the table, and another user or process is trying to access it simultaneously.
  Cause:
  
  User Lock: A user is currently editing or processing data in the specified table, which prevents other users from accessing it.
  Long-Running Transactions: A transaction that takes a long time to complete may hold the lock for an extended period.
  Uncommitted Changes: If a user has made changes to the table but has not yet committed those changes, the lock will remain in place.
  Background Jobs: Sometimes, background jobs may also lock tables while they are processing data.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for the user to complete their transaction may resolve the issue. You can retry the operation after some time.
  Identify the Locking User: Use transaction code SM12 to view the list of locks. You can identify the user who is holding the lock and the specific table that is locked.
  Contact the User: If possible, contact the user who is holding the lock to see if they can complete their transaction or release the lock.
  Release the Lock: If the locking user is not available or the lock is no longer needed, an administrator can manually release the lock using transaction code SM12. However, this should be done with caution, as it may lead to data inconsistencies if the user is in the middle of a transaction.
  Check for Long-Running Transactions: If the lock is due to a long-running transaction, investigate the transaction to see if it can be optimized or if it needs to be terminated.

  Lock Management: Understanding how SAP handles locks can help in troubleshooting. SAP uses different types of locks (exclusive, shared) to manage concurrent access to data.
  Performance Tuning: If locks are a frequent issue, consider reviewing the performance of the transactions that are causing locks and optimizing them.
  
  Always ensure that any actions taken to release locks are done with a full understanding of the potential impact on data integrity and system performance.
