Can we make Oracle calculate schedule ship date on a drop ship scenario

Hello Everyone,

Here is what I need help with. I have to have Oracle calculate the schedule ship date based on the customer request date and transit time for drop ship order and wonder how can I do that. There is no ship from warehouse on the sales order line and the transit times that we setup works with ship from and ship to.

This is required because the seller is responsible to arrange the carrier and need to inform when to pick up the load from the supplier site to make sure customer receives the product on the date they want.
