Business Function Set: Enterprise AddOns in Solution Manager

Hello

For testing purposes I want to activate the Enterprise AddOn EA_PLM in transaction SFW5 inside a Solution Manager 4 installation but no Enterprise AddOn is available. Additionally there is only one Business Function Set called "telco reference pack" with two Business Functions. Do I have to set up something before I can active the Enterprise AddOns? I thought PLM is part of the Solution Manager 4 installation.
