Select the Levels tab to access the Levels options.
The Levels tab can be a little intimidating at first glance. What Levels controls is the amount of breakdown you would like for the Summary. There can be up to 6 tiers of breakdown. After the Summary is run, when the Summary file displays, you will see these levels represented as a "tree view" on the left side of the Summary File Maintenance (SFM) window (example in Figure 1).
This example shows that the Summary was run with three levels: Drawings, Sections, and Category. Notice that Drawings is the first level, Systems is the second level, and Category is the third level. Levels are tiered according to their selected order. Therefore, as Figure 1 shows, the Category level is a sub-level to Sections; Sections is a sub-level to Drawings. If a fourth level had been chosen, it would be a sub-level to Category, and so on.

Note: The Levels section and its functions are explained in more detail later in this topic. See Levels in the Summary Setup topic.
Once you select a level, notice that the choices in the Sorting & Filtering section change.
Sorting & Filtering is a way of further narrowing
down your Summary. You can either leave all of the descriptions (Drawings,
Category, Installation Codes, etc.--whatever level is displayed) selected,
or you can pick and choose just certain ones to be included. You can also
use the 
and 
buttons to shuffle
the descriptions, determining in what order they appear in the Summary.
This is another way that different Report Types come in handy. You could set-up different Report Types containing all Systems or just certain Systems. Summary is very flexible and very customizable to your specific requirements.
