Over delivery Tolerance in CO08 is not working

Hi gurus

My client is using AFS module, my requirement is to restrict the order confirmation beyond the specified limit as over delivery tolerance maintained in material master on work scheduling view tab page.

When I create the production order using t code CO01 system copies the Over.Delv data from material master to order, but when I am creating a order with respect to sales order using CO08 the over delv is not getting copied into order.

Please help to resolve the issue

Regards
