Inventory open quantities

Before i close the inventory for a specific month, i run the “check open quantities” to check how many inventory will still be open after the inventory closed.

i got a report like below:

On the figure above, i high-lighted two quarantine orders which on the “Open quantity” report. These two records are related to a purchase order.

the end date is 9/30/2014. from my point of view, for those items that were physically received but not financially updated items before 9/30/2014 will be listed in the report.

Here is the inventory transactions:

All these quarantine orders’ transactions happened in Oct/2014.

Why the open quantity get these transaction involved ?

many thanks.
