Hey Martinique,

Yes that is right. The important thing to remember is that those numbers match the mdl_user::id database field not the idnumber field that you can set in the profile. And that it should follow all the way up the tree, so if 0000 had a manager you would have to add him beforehand as well and so on and so on.

Note: This is not reccomended, there are totara core api functions (like assign_user_position) that you could use through a small php script instead of running sql straight on the database that would make this a lot safer, and probably easier.

Hope that helps
David
