The financial reporter is not designed to show balances in the middle of a period, only at the beginning or end. For that matter, the standard reports such as the Trial Balance and Detail Listing are not designed that way either.
You will have to use a custom reporting tool and design such a report. The two Adagio custom reporting tools are Crystal Reports for Adagio and Adagio Gridview, and either one will work. Crystal Reports will make presentation quality reports but has a steep learning curve. Gridview is easier to learn and use and the report will be spreadsheet-like rather than presentation quality.
If you have not worked with either program, you will probably want your Adagio consultant to help you.
