I am working on a scenario which need different modes of transport like road and rail, we want to plan forwarding order from source location A to destination location D. We defined two routes between A and D, first route is using transshipment location B and C, that is A to B to C to D as a route, and all are using road. Second route is using transshipment location rail_1 and rail_2, that is A to rail_1 to rail_2 to D, and from rail_1 to rail_2, we are using rail, and from A to rail_1, and rail_2 to D, we are using road. The requirement is that we want to display both route in the transportation proposal for the forwarding order, and compare which one is better.
However, while creating a forwarding order from A to D, if we select road as a transportation mode in the general data, the proposal only shows first route, which is road only. If we select rail as a transportation mode in the general data, the proposal only shows second route, which is combination with road and rail. If we don't select a transportation mode in the general data, we will get an error that transportation mode is missing, planning is blocked.
Is there any way we can display two kinds of route in one proposal?
