As production orders are independent, they will be transferred to new period completely.
The slips in "planning" status, related to production orders and belong to new period date, will be transferred to new period. These slips will be deleted from previous period. However their production order connections will be transferred to new period.
"Planning" status slips' information at material status window will be updated according to the transferred slips. That is to say previous period dated slips' quantity total (in "planning" status), displayed at material status window, will not be transferred to new period.
