Hi @MonikaS9010,  

Obj refresh and lock : This feature is basically to get the lock on an instance which is already opened or already not locked , If the Obj-Refresh-and-Lock fails to acquire a lock, this page is created and can be viewed with the Clipboard tool or the Tracer. Page name is “Lockinfopage”.It is used when a user is. not sure that a user acquired lock in the instance or not ?

In case lock is not acquired then it acquires lock on that instance. If lock acquired then it will only refresh

But in case of Obj-open we need to handle lock manually while opening the instance to update anything. It never check lock is acquired or not. Thanks | Somil
