Reschedule report from last know successful run

Im fairly new to BO, but I need to schedule a report to pick up data twice a month. It would be nice to pick up data from where the last successful report ran to alleviate duplicate rows, date overlap, being sent. Does anyone know if that is a possibility? if so, how?

If you are outputting to WebI format, you can use the data tracking features to compare the data in the current report to the prior run.
