long treatment to do, all users are blocked

I have a long treatment to do, in this treatment there is a lot of modifications to do on the tables, so all user which use these tables are blocked with a message (there is another user which modify the table …)

I checked the code there isn’t any “locktable” in the code !!!

So isn’t better to add recName.locktable(true) before the modifications ? (I think with locktable(true) Navision will create a queue for all task blocked because of the treatment ?!
