Overlayable and non-overlayable objects

This topic provides information about which objects and associated definitions you can or cannot overlay. These objects are called granular components and you can customize these granular components of the overlayable objects.

Overlayable objects

You can create overlays for the following objects:

• Active links
• Active link guides
• Associations
• Deployable applications
• Escalations
• Filters
• Filter guides
• Forms
• Fields
• Images
• Local applications
• Menus
• Packing lists
• Views
• Web services

When you create an overlay of an object, its granular components receive a default type that is usually No Overlay. The granular components inherit their definitions from the origin object. After creating an overlay of an object, you can change the overlay type of any granular component (for information about overlay types, see Granular overlays). The granular components of the objects and the applicable overlay types are listed in the following table.

The overlay type No Overlay is available for all overlayable objects listed in the following table. Setting the Overlay Type to No Overlay reverts the customizations set for the selected object. The object inherits the properties of the base object.

The following table lists AR System  overlayable objects, their overlayable granular components, and whether they can be an additive or overwrite type of overlay.

AR System  overlayable objects

^{1 You cannot reset this definition on a join form; it must be inherited.}

Other Definitions refers to all other components of the object. The overlay type selected at the Other Definitions level applies to all the object definitions contained in it.

Non-overlayable objects

You cannot create overlays for the following items:

• Custom objects
• Overlaid objects—You cannot create multiple overlays for the same object.
• Overlay objects—You cannot create overlays of overlays.
• Form data—Distributed Server Option (DSO) mappings, DSO pools, flashboards, skins, and templates are stored as data in a form. Because AR System  does not support data overlay, you cannot use overlays to customize form data. Any modifications that you make to the form data might be lost when an application or server is upgraded.
