I got very strange issue today.
I maintained in Customer master under Unloading point tab , a unloading point with factory calendar.
When I used this customer to create SO(Sales order) , then the Route Schedule is not appearing in SO.
But, once i removed the unloading pont-factory calendar from customer master, then Route Schedule is appearing in SO for that Customer(Ship-to-party).
Is it a standard behaviour of SAP or am i missing something.
