How to constrain assignable resources by color of the item to be produced

Steps:

1.In the “Spec” field of a resource, enter information about the spec that the resource can produce. If there are multiple specs that the resource can produce, specify them by separating with semicolons.
2.In the “Spec” field of an order or item, specify a single value as the spec of the item.

In the “Num spec” field, you can specify other characteristics of items that can be expressed in strings, such as shapes and surface treatments.
If the spec value specified in an order or item matches one of the spec values specified in a resource, the order is evaluated as assignable to that resource.
If the spec field is left blank, Asprova will treat the order as assignable to any resource.
