How do old product names map to Infor products?

So I basically inherited an audit, Infor wants to audit all of our "S3" stuff, but I'm NOT a Lawson guru and I can't figure out what all they want to audit. For example our POF has "Vendor Self-Service" and "Purchase Order" -- is that S3? How can I tell? Is there a list somewhere of all the products that are S3 products? There's not much helpful on infor's web site, they have no support and the content is all market droid junk. None of the supply chain stuff seems to match up.
