Adding Resources to a Resource File
When you create a new resource file, Open Plan displays a window containing an empty workspace.
To add a resource to the file, click the Add Resource command on the Edit tab, or double-click an empty area in the workspace.
Although you can define a resource file as a "flat" structure in which all resources occupy the top hierarchical level, a more common practice is to develop a tree-like breakdown structure that can be used to summarize pools for reporting purposes.
Open Plan makes it easy to work with hierarchies of resources. For example, you can assign an entire group of resources to a different resource pool by dragging the resources to a different position in the resource hierarchy. You can also expand and collapse individual resource pools in order to display the appropriate level of detail.
