When I enter a deadline on a sales order (a service with the following invoicing policy):

I would expect the deadline to show up in Project's tasks but it isn't.

Is this normal behavior?

To solve this I have to enter the deadline again for each task.

Furthermore, when I add a sales order using the calendar option, the day cell I selected doesn't even show in the sales order information.

I think is unexpected behavior.

Would anyone please have any ideas or suggestions regarding this issue?

Thanks
