Problem with Date flow filter in Item table of Nav 2015 w1 version

Dear Experts,

I am facing a problem with (DATE FILTER) flow filter in item table. I have tested at item card also. The problem is based on date filter Inventory is not changing.

Please confirm is there any product bug. If this is a bug then please help me with some customisation for creation a page for inventory from item. In this page inventory should change based on Date Filter.

This is NOT a DateFilter problem or bug - Inventory List has always (mean all NAV versions) shown a sum of all entered transactions in Inventory field.

There has never been such functionality in Inventory for quantities like Balance at Date in CoA for amounts.
