Maintaining Variant Routing Rules
Use Variant Routing Rule Maintenance to define selection and assignment rules for operations in the generic routing.
If no selection rule has been defined for an operation in the generic routing, the variant product structure always includes the operation.

Variant Routing Rule Maintenance
To select an operation of a generic routing:
1 Specify a configurable item number in the Configurable Item field. The item’s description displays next to the configurable item number. The routing table below lists all the operations in the item’s generic routing.
If an operation already has selection and assignment rules defined, they display in the Selection Rule and Assignment Rule columns respectively in the generic routing table.
2 Click the operation whose selection rule or assignment rule you want to edit.
Defining Selection Rules
Define selection rules under the Selection Rule Tab.
To edit a selection rule:
1 Type the rule in the Selection Rule box. Use the Rule Assistant to assist you in the process. See Using the Rule Assistant.
2 Click Check Syntax to validate the rule syntax. If syntax check is successful, Status changes from Not Run to Passed. If syntax errors are found, error messages display and Status changes from Not Run to Failed.
3 Click Save to save the rule. On saving the rule, the system performs a syntax check on the rule. If syntax errors are found, error messages display.
Defining Assignment Rules
Define assignment rules under the Assignment Rule tab. You can define multiple assignment rules for an operation.
