Add additional fields for products, possible?

[cybersky]

I have products I am adding into my store that have addition fields of data to record/be displayed in the admin.

For example, a product has a SKU and a manufacturer, easy, but I need to add a manufacturer SKU as well.  We change the manufacturer SKU to an internal number, and need to have both SKUs in the system.

Is it possible to add more fields for products, and if so, how?

Thanks,
Bill
