I'm not sure that you can run stored procs with this method. I could be wrong but I prefer using "do-sql" when I need to do this because I tend to be somewhat untrustworthy of DataDeploy.do-sql is in the documentation and it allows you to write a chunk of arbtirary SQL instead of doing the traditional field mapping. You can get as crazy as you want to with it, too... if your SQL chunk works in your query tool, it will work in a do-sql block, as well.
