Within Dimensions most reports will only go as far back as last year due to the limitation of years.
It bundles all old data into Year "O" or "Other". To view these transactions please see steps below.
Select Home menu option
Click Financials, Nominal Transactions.
On the left, next to the View option, click the down arrow icon. This will show you a list of Last, Current and Next Year, and Earlier.
Any transactions marked with '0' are earlier transactions.
We don't have any generic outputs for historical data unfortunately, unless a report was designed specifically to do that.
