Last Event or Task Date vs. Last Activity Date

Salesforce gives users the ability to run reports on the Last Activity Date for all objects, out of the box. But what if users wanted to distinguish between Last Event Date vs. Last Task Date? Or break up the data by other criteria?

Luckily, the Declarative Rollups for Lookups package (thanks to Andy Fawcett) can solve this problem, with only a few minor tweaks to work around a Salesforce limitation: field ActivityDate does not support aggregate operator MAX.

The general idea is to create two custom fields on the object of your choice: Last Event Date and Last Task Date. Follow these up with two Lookup Rollup Summaries, and you can now easily split your activity data by Tasks vs. Events. The end result? Reports like the following.
