User Defined Picking and Ship Confirm for Revision Controlled Items

Hi

I am working for a Automotive Customer, they are using Items with Revision controlled.

Example:

Item No / Revision No / Qty

ITEM1 /  00 / 15

ITEM1 / 01 / 35

ITEM1 / 02 / 25

As per the above data, Customer want to keep the stock ITEM1 / 01/ 35 for Spares Demand, not to used for regular sales orders along with latest release.

When I enter a Sales Order for ITEM1, system will pick stocks of all the revisions based on Qty in SO Line.

Is there any way to Restrict the Picking based on Revision?. so that the Stock related to Spares not touched / Picked by the system.

regards,

Ramakrishna.
