Stock date of existing Lot number not updating at the time of Receipt !

Hi,

If we receive an item to an existing Lot, Why the stock date and Expiry dates are not updating automatically to the date of PO Receipt. ?

This will make an issue of Auto-allocation in OE, system will take this Lot ,even it contains the latest stock.

Situations like , if we po receive 2 separate items to same lot number(pallet as lot), then the Lot number we used might be already exist for one of the item with an older stock date. Otherwise we have to generate each lot number for 2 items
