Yes it takes into account all tasks within the parameters whether they are collapsed or not. You have selected resources and you have a date range. Sorry but I don’t know of any other way…hmm. I guess you could have multiple projects with a shared resource pool and then level only one or some of the projects. I’m not saying it’s a good option but it’s an option. Microsoft levels only open projects and leaves closed projects for the same resources as locked. Does that help…???
