Hi All,

What is the difference between aggregation and roll up aggregation?

The "Aggregation" property is what will be applied on that data item when displayed on the detailed lines of a report (i.e. rows of list)

...The "Rollup Aggregate Function" is what will be applied on that data item on a summary line of a report (i.e. list group footer).
