Constrain Product Quantity

The Constrain Product Quantity template has the form:

[The quantity of a product] [=] [a value]

The template has three parts. The first operand names the product.

The operator, [=], defines how the product quantity is related to the third operand, [a value]. The operator is limited to numeric comparisons ( =, <, >, and so on).

The [a value] operand can be any of the following:

• The quantity of a product in the solution
• The quantity of items from another relationship in the solution
• The quantity of items in the solution from a class within a relationship
• The value of an attribute (the data type for the attribute must be number or integer)
• A number

The "Insert a" tab provides two sets of arithmetic functions that allow you to combine these items. For example, you could write the following rule:

The quantity of Item A from Items Class <= the quantity of Products-Class items

In this rule, "the quantity of item A from Items Class" is the first operand. It names Item A in the Items class. The second operand is "<=".

The third operand is "the quantity of Products-Class items" and refers to items in the Products class. This class is contained within a relationship in the customizable product.

The rule states that the quantity of Item A in the solution must be less than or equal to the number of items from the Products-Class in the solution.

Use Constrain Product Quantity rules to set limits on the quantity of products that can be in the solution. The limits can be defined as a number or as the quantity of other items, or the value of an attribute.
