Asset Management

We are running SD 7015.

I'm new to this - the previous person responsible for managing the product is no longer working with our company.

I've got an issue with inventory. Hard drives and various other system components somehow have been entered as workstations which is throwing my workstation inventory way off base. and I'd like to get that changed. Now I've gone to admin > product and changed the various components product type from workstation to "x,y,z" so future inventory will be properly identified.

Question is how do I get the old inventory to move to the proper product type? I don't see any easy edit process nor is there an ability to "scan" the product. Do I have to delete it and add it back?

Thanks.
