Value

The value operand defines the quantity to be contributed to the target. The Constraints view provides several methods for determining this quantity:

• You can explicitly state a number as the value.

• You can define the value as the quantity of another item, or the value of an attribute, linked item or resource. For example, you can provide three times the quantity of Item B to Item C.

• The value can be an expression that resolves to an amount. This amount is then contributed to the target. For example: When a condition is true, it provides Relationship A, Attribute Color = Red to Item B. This constraint means that when the condition is true, then each item in Relationship A for which the attribute Color = Red that is added to the solution, increments the quantity of Item B by one.
