Reports are only useful if they can be interpreted quickly and accurately.  It is both cumbersome and error-prone to be forced to scroll through tens or hundreds of records looking for certain ones.

Bank Reconciliation allows you to group report data on many different fields to see a breakdown by category.

In the sample below, Report Creator is showing the Unmatched items (period sensitive) report, and the data is grouped first by origin (Bank or G/L) and then by Period.  This means that all the records are put into two groups, Bank or G/L.  Next, still inside the respective groups, each of the records is ordered by Period.

To create or remove a grouping

Creating or removing a grouping is as easy as dragging the column heading to the grey bar (to group) or dragging it back to the grid (to ungroup).
