Directionality of Operators

Rule Operators* function between the [LHS] and [RHS] and possess a characteristic of directionality that determines which side of the Rule becomes its "target".

Uni-directional Operators imply that the [LHS] affects the [RHS], and that when all of the elements in the [LHS] are selected in a product configuration, the [LHS] is triggered to operate upon the target elements contained in the [RHS].
Bi-directional Operators imply that Rule elements on either side of the Operator can assume the role of [LHS]. Bidirectionality occurs in only two cases:
1. All instances of the Can't Work With Operator
2. The Removes Operator, when the [RHS] is NOT an Included Part in the Product Definition

This characteristic of directionality combines with Rules' AND/OR/NOR characteristics, and results in a high degree of Rule-making flexibility. As you can see from this table, special attention must be given to the use of Parts and Part Classes that are classified as Included in the Product Definition, and to all Removes Rules in general.
