That sounds like pessimistic locking. WO is more oriented at
optimistic locking, but that can get complex to handle with you have
multiple instances (EOF handles this differently when conflicts
happen within one EOF stack and when they happen across EOF stacks).
I'd work out how to deal with the optimistic locking failures. You
can find how to do this in EditingPage.java in the GVCWOExtensions
framework. I am not sure what, if anything, Wonder has for this.

Assume multiple people have the access for changing the table
remotely.

Locking is at the editing context level. What are you trying to do?

Is there a way to lock an entity to prevent other accesses to it

Thanks
