Where does the function 'getSalesEntityType' come from?

Ah that was my understanding, yes. It's just that I didn't see any includes in the file. But I can assume that when inside workflow tasks, the workflow system has already included many functions. Come to think of it, I was looking at this as if the function were the starting point. I should look at it more as if the function file is the inclusion (before which many other inclusions may have been made).
