Order Processing in the backdate

Hello,

My client wants to enter order in the back date, but the system is not building shipments in the backdate.

Whenever I try to make a Bulk plan, the system fails to plan that. Whereas if I create shipment through routing option, it creates a shipment, but shows its status as "Will not meet Service Time".

Consequently, I may be able to create its shipment forcefully, but then I cannot assign any driver, Equipment or power unit on it.

But my client says that they cannot enter future orders into the system, because it will be next to impossible for them to enter orders in advance.
