Is SAP SCM 5.1 and SCM 2007 are same? Please Confirm.

Hi,

I have to Install SAP SCM 5.1 Non-Unicode System, but I cant find Installation Media at Marketplace instead I can find SCM 2007. I am able to get SCM 5.1 SPs when I clicked SCM 2007 entry on Marketplace. So please confirm whether these 2 products are same or not?

If yes, Please provide a link/ note that shows SCM 5.1 has renamed to SCM 2007 from SAP.

Thanks.
