Unit "Setup(s)" are part of the "Setup" procedures that will likely be overseen by the organizational supervisor.   All responses in the Chattels program shown along the left side of the image MUST be addressed to value Subjects with equipment, commodities, or "others" such as "Accounts", i.e., payable versus receivables or mobile homes.

All commodity and other chattels must be tied to a specific UNIT.  The example above covers most of the common types, but if you find something that is not valued in the final stages of your ownership's chattels, it may be due to NOT defining the Unit you have entered in the Subject Description and you will have to go to this Setup Screen and enter the appropriate Unit.
