A process routing’s stock selection module is associated with one of the routing’s nodes. Typically, a routing’s stock selector is associated with the process called Material Stock. In some cases, to allow different routings to have different stock selectors, multiple nodes have stock selector modules, but only one is evaluated by the cost engine for a given routing.

The simplest way for a routing to designate the stock selector node is by the presence of the node attribute utilizationProcess, where the attribute has no value. If there is more than one node with this attribute (and they are all valueless), the cost engine treats the right-most active one as the stock selector node.

A routing can also designate the stock selector node by specifying the node’s name as the value of utilizationProcess for some other node in the routing. If there is more than one node with a value for this attribute, the left-most one specifies the name of the stock selector node.

For example, for the sheet metal process group, if a routing includes the branch node Prog Die, which has a node attribute utilizationProcess whose value is Progressive Die, the cost engine evaluates the stock selection module associated with Progressive Die (assuming no other node has a value for utilizationProcess).
