This test verifies the behavior of alternate flows. An assembly operation is modeled which has alternate components:
- Component A or component B can be used in the assembly, A being the preferred one.
Component B is only used when constraints are found on A. - Component C can be replaced by component D till a certain date, or by component E valid from a date.
The validity periods of the components D and E can overlap. - Component F is used till a certain date, after which the component G is used.
The validity periods of the components can overlap.
