reference
 A link from one object to another type of object. In the same way that
		you can add items to a formula on the Item
			Lines tab, you can add other types of objects, such as companies or
		specifications, on the References
		tab of the Formula form. You can edit a reference
		directly from the References tab.
		You can create a copy of the referenced object without leaving the References tab. Most Optiva
		objects can reference other objects. You configure the types that are available.
