Object requested is currently locked by user ABCD
Message no. MC601
Diagnosis
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 = WXYZ
COLLISION_UNAME = ABCD
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.
Procedure
Look in the lock table to establish which user or transaction is using the requested lock (Tools -> Administration -> Monitor -> Lock entries). You may need to contact the user in question.
