Incorrect Schedule ship date, not considering delivery lead time.

Hello All,

I am struggling to find the cause for one of issue where for one Customer, schedule ship date is not populating correctly. Please see below example:

X is our customer.

Create the order line for this customer with request date as 24th Jul'15 (FRI) since customer can receive only on Friday. When we schedule the line, it calculates the Schedule ship date / Promise Date as 24th Jul'15 23:59:59 without considering delivery lead time which is 2 days.

On customer ship to site, Request Date Type is "Arrival" , We have also assign shipping calender to this customer site which specify to ship only on Wednesday. Still issue exists, Any help resolve this issue highly appreciated.
