I would like to share eSAM process for make correct understand and please follow the step.
1.After request for ship >> Planer will create SAMs.
2.Loop approval around 7 days.
3.Send Part to Shipping Department for pack and booking flight.And next day will ship part.
****Planner will estimate ship day D+7 days (count from the day of created SAMs).
Because We can't to know when SAMs's approve done.
If we define short time will effect with Shiping Dep (why ship late?).So we should give lead time for loop approval , pack and booking.
In case approval is done soon (before 7 days), We will ship immediately.
