non standard wip job on hand quantity

Hi,

i have a query regarding wip repair mode

if We receive the item against Repair Order in One Sub inventory. (Repairable Stores). After repair  (WIP job completion), we  move the item to Finished Goods Stores. Now System onhand has Qty of 2 .

(1 from the receiving and 1 from WIP completion).  This is of course wrong.).Actually it is a same item.

When We create WIP job, is there a way to issue out the material from Receiving Subinventory (Repairables Stores). However physically we move the item from  Repairable stores to Shopfloor.
