Process orders in the weekend moving during the night in APO/PPT1

Question

Hello Gurus,
I have a problem on the scheduling of production orders when these orders are scheduled
on the week end.
Problem description: 
On day 1 the short term planner schedules production orders in PPT1 (APO) on the
week end.
During the night these production orders are re-exploded in ECC (see: COR2 => Read
Master Data)
On day 2 the end production date of orders that were in the week end, have moved
by the system to the Sunday night.
Step 1: The order is scheduled on the week end on Saturday 14 March 2015.
Step 2: We explode the order in ECC
In ECC, we have:
But if we check the order in APO, we have:
You can see that the process order are placed at the night of sunday, also if in ECC after explosion was always where was planned.
Have you any idea how to avoid that the process order moving in APO ?
Thanks Gurus.
Livio
