What platform version is it? What do you mean by “Can’t delete”? Is it not working? Do you have an error message? Can you share the tracer output XML for analysis?

Well looks like you need a lock to delete this instance right? Can you get the lock first before actually deleting?

Your Obj-Browse is giving you a list of instances with appropriate keys for locking I guess. So you need to loop on each result page and Obj-Open-By-Handle to lock I think.
