What causes this issue?

A lock requested by calling an ENQUEUE function module cannot be set up
because another SAP transaction is using the lock in question.
Technical Information: The C_ENQUEUE routine returned the following
values:
COLLISION_OBJECT = &V2&
COLLISION_UNAME = &V1&

System Response

The ENQUEUE function module triggers an appropriate exception. If this
exception was not intercepted by the application program, this leads
automatically to the active SAP transaction being cancelled.

How to fix this error?

Look in the lock table to establish which user or transaction is using
the requested lock (<LS>Tools -> Administration -> Monitor -> Lock
entries</>). You may need to contact the user in question.

• What is the cause and solution for SAP error message MC601 - Object requested is currently locked by user & ?

  The SAP error message MC601, which states "Object requested is currently locked by user &," typically occurs when a user attempts to access or modify a resource (such as a material, document, or transaction) that is currently locked by another user. This locking mechanism is a part of SAP's concurrency control to ensure data integrity and prevent conflicts when multiple users are working with the same data.
  Causes:
  
  User Locking: Another user is currently editing or processing the object, which prevents other users from making changes.
  Session Timeout: A previous session may not have released the lock due to a timeout or an unexpected termination.
  Background Jobs: A background job may be running that is holding a lock on the object.
  Transaction Errors: An error in a previous transaction may have left the object in a locked state.
  
  Solutions:
  
  Wait and Retry: If the lock is temporary, waiting for the other user to finish their work may resolve the issue. You can try again after some time.
  Identify the Locking User: Use transaction code SM12 to view the list of locks. You can check which user is holding the lock on the object and, if necessary, contact them to release the lock.
  Release the Lock: If you have the necessary authorizations, you can manually delete the lock entry in transaction SM12. Be cautious with this approach, as it may lead to data inconsistencies if the other user is still working on the object.
  Check Background Jobs: Use transaction SM37 to check if any background jobs are running that might be holding the lock. If you find a job that is causing the lock, you may need to wait for it to complete or consult with your system administrator.
  Session Management: Ensure that your sessions are properly managed and closed when not in use to avoid unnecessary locks.
