I am having a problem with certain shop orders that when Using the infinite scheduler, when I put in an earliest start date, it automatically sets the SO start date to a day earlier than the Earliest start date.  I have not Queue time on any operations and cannot figure out why IFS is doing this,

If you have the Scheduling Direction set to Backwards Scheduling, the Earliest Start Date is not used in the scheduling logic. Instead the system schedules the operations backwards from the Need Date and updates the Start Date according to when the first operation on the order is scheduled to start, which may very well be before the Earliest Start Date

Earliest Start Date takes effect on the scheduling only when you have selected Forward Scheduling. Then the operations are scheduled forward from this date, which may in turn result in an order that is scheduled with a Finish Date later than the Need Date.
