Quentity tracking in Disposition

Hi,

setup -I am using Receipt routing and update on hand is my Stock stage which come after Dock > Inspection > Inspection complete > stock

Question -

Now, In disposition screen I have five buckets to dispose if I don't want to make return order after entering quantity in any of the bucket  which is the place where I can track quantity I disposed on any of rework or scrap or any bucket.

Lets say I received 100 at dock and I want to dispose 10 and process 90 for in stock, I am not able to see 10 quantity in any bucket.  I am not willing to create credit order.
