Use old product number for new product.

Dear all,

I have to manage the following case.

From a defined date the engineering releases a new product that will substitute an old product.

The marketing doesnu2019t want to change material number and would you like to use the old product number also for new product.

This solution has a great impact for planning because there is not possible to distinguish the old product stock from new product stock.

Could you help me?

Regards
