Symptoms

ACTUAL BEHAVIOR
Observing Schedule Orders with LINE_ELIGIBLE mode does not always respect First
and Second Order by criteria.

OBSERVATION
End users are reporting that when running the Schedule Orders program with only the following parameters:

Operating unit,
Scheduling Mode = Progress Lines at Schedule-Eligible Activity,
First order by = Request Date,
Second order by = Creation Date

Observe > the sales order lines selected for scheduling and successfully scheduled are not always respecting
  the order by condition when available supply is lower than total demand.

Have an issue with "Schedule Orders" program run with Scheduling Mode = Progress Lines at Schedule-Eligible Activity, not Reschedule.
It happens when the other parameters passed to program are limited to:

Operating Unit =
Booked = Yes
Scheduling Mode = Progress Lines at Schedule-Eligible Activity
First order by = Request Date,
Second order by = Creation Date

and not any other.

It only happens when have several Schedule-Eligible sales order lines for the same item/warehouse/demand class combination and the total ATP supply is not sufficient to fulfill them all at once.

Issue does seem to stop when: Included Pick Released Lines parameter is set to N/No instead of Yes or Null.

EXPECTED BEHAVIOR
Expect the system to schedule the order by conditions successfully (honor older request date lines first), but randomly this is not what happens and some of the latest entered/booked order lines are scheduled before older request date ones.

STEPS
1. Responsibility: Order Management Super User
2. Run > Schedule Order Program

  Parameters:
  Operating unit,
  Scheduling Mode = Progress Lines at Schedule-Eligible Activity,
  First order by = Request Date,
  Second order by = Creation Date
