Error " Change the inspection stock of material 20000 in qm only"

HI All

I have a material with Quality management view.

I did a PO for 01 qty.

I created a inbound delivery for 01 qty.

The stock had been placed in Qua.ins stock.

I transfer posted the material from Qua.ins to Un res stock.

Now i am trying to reverse the delivery using VL09.

I got a error message that deficit of 01 qty in quality stock.

Now i tried to transfer post the stock from Un res to qua.ins stock.

I am getting the error "Change the inspection stock of material 20000 in qm only".

I found the inspection lot.

The status is UD ICCO SUB SPCO CLAS STUP.

How to proceed

Help me in this regard.

Regards

KK
