I was reading documentation on tips for using MSP Schedule Connect with Clarity PPM. One tip was to enable the PM to track any task start/finish date changes which occur through export/import commands, by mapping "Prior Start" and "Prior Finish" Task attributes to Start10 and Finish10. This sounds great - except for the fact that I cannot locate "Prior Start" or "Prior Finish" attributes anywhere - on the Task object or any other object for that matter. What am I missing?
