quality inspection wrong posting

Hi all,

I have created an Inspection Plan, characteristics and assigned to a material,,,

scenario:

1. created a PO for 100 qty

2. GR to quality inspection stock - 100 qty,,, quality inspection lot is generated.

3. QA32 - i need in the following way:

GR Qty = 100

uninspected stock = 20

Unrestricted Use = 60

Blocked stock = 12

retun delivery = 8

after posting the usage decision,,, the uninspected stock (20) is also going into unrestricted use i.e (60+20),

what may be the reason? urgent,,, need help immediately,,
