When you first assign a project to a user, the user has access to all WBS elements in the project. In large projects, this may represent a large amount of information that can take some time to display and process. To speed processing, you can limit a user's view of the WBS structure to only the elements the user needs to see.
You can restrict access to the WBS elements using the WBS Restrictions dialog box, or by assigning a WBS Equivalent User to the project.
To limit access to WBS elements, complete the following steps:
