Work Order Resource Not Showing in Plan Resource Requirements

Oracle 12.2.9, CUM#20

We have a single work order that has resources in the routing operation 50. However when we run the plan we cannot see the resource requirements for that operation in the planner workbench resource requirements.

Things we have ruled out (and identified as other reasons for the plan not to consider the resource requirements of a work order.

-- The work order is active/open and not recommended for cancel

-- The routing operation is scheduled

-- The recommended reschedule is still well within the plan horizon

We did discover that the work order routing step was "Option Dependent" and we don't use options during the ordering process. So we updated that field, re-collected (full collection) and re-ran the plan. No luck.
