Working with Folders in Model Designer
You can organize entities, perspectives and other folders into folders within your report models. This allows you to expose frequently used model items, group related items, and archive inactive or infrequently used items to facilitate navigation for your users.
You can place the folder anywhere within the entities list or, you can nest a folder within an entity or another folder. When you deploy the report model, you can assign permissions to the folder so that it is not visible to all model users.
