Table 1: Terms
| Term | Definition |
| Effectivity | Identification of valid uses of an item in a structure if it is conditional. |
| Effectivity Variable | Variables that influence effectivity decisions, such as date, model, unit, batch, lot, plant. |
| Effectivity Scope | Built-in ItemType that represents a list of relevant Effectivity Variables. |
| Effectivity Expression | Expression representing the effectivity condition in the Boolean Expression Language. For example: Model = “Model X” and (Unit >= 10 and Unit <=20) |
| Effectivity Criteria | Criteria used for resolving a structure by effectivity. Effectivity conditions set on relationships are evaluated against the input criteria to determine the inclusion or exclusion of conditional items in the resolved structure. For example: Model = “Model X”, Unit =15 |
| Scope Object | Instance of the class “Aras.Server.Core.Configurator.Scope”, and is a container of Variable instances. |
