Marketing Prospects in Campaigns

Hi All

I have created Marketing Prospects and the respective target group using ELM. Now when i add this Target Group to my campaign it gives an error "selected segment is not a valid business partner segment"

Also i wanted to know the following:

1. Is their a process by which i can automate Marketing Prospect to BP Conversion?

2. Can i assign Marketing Prospect to a Call List and execute outgoing calls?

Thanks
