How To Fix FMAVC124 - User &1 locks &2 (&3)

SAP Error Message - Details

• Message type: E = Error

• Message class: FMAVC - Message class AVC funds management

• Message number: 124

• Message text: User &1 locks &2 (&3)

What causes this issue?

Availability control requests a lock by calling the ENQUEUE function
module ENQUEUE_E_EFMAVCT. This lock 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 = E_EFMAVCT
COLLISION_UNAME = &V1&
The lock object refers to the budget address &V2& in the cover group
&V3&.

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.
The lock table entry in question uses the technical object number &V4&
in the lock argument.
Since the ENQUEUE module ENQUEUE_E_EFMAVCT is called with the parameter
_WAIT, you may also try to avoid the observed lock collision by changing
some system parameters (see note 6822).

• What is the cause and solution for SAP error message FMAVC124 - User &1 locks &2 (&3) ?

  The SAP error message FMAVC124 indicates that a user is trying to access or modify a locked object, specifically a commitment item or a budget-related object. The message typically reads: "User &1 locks &2 (&3)", where &1 is the user ID, &2 is the object being locked, and &3 is additional information about the lock.
  Cause:
  
  Concurrent Access: The error occurs when multiple users attempt to access or modify the same budget or commitment item simultaneously, and one of the users has locked it for editing.
  Transaction in Progress: A user may have an ongoing transaction that has not been completed, which results in the lock being held on the object.
  System Configuration: Certain configurations in the system may lead to locks being held longer than necessary.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for the user holding the lock 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 identify the user who is holding the lock. You can check the lock entries and see if the user is still active.
  Contact the User: If possible, contact the user who is holding the lock to understand if they can release it or if they are still working on the transaction.
  Release the Lock: If the locking user is no longer active or if the lock is stale, a system administrator can manually release the lock using transaction SM12. However, this should be done with caution to avoid data inconsistencies.
  Review System Configuration: If this issue occurs frequently, it may be worth reviewing the system configuration and user access patterns to minimize locking conflicts.
