Divided Trial Balance report in AX 2009


I have a question about the use of Divided Trial Balance.

I am unable to understand how to use this report. I found From Date and To Date repeating in the report, but no idea as to why it is repeated. Please tell me about the fields is this report


The first are the balances for the last month in the Specified period and the second one is the balances for the specified period.

Example - from date 7/1/2010 , to date 3/3/2011 (MM/DD/YYYY)

The first one will show the balance for 3/1/2011 - 3/3/2011(last month start date - to date)

and second will show balance for 7/1/2010 - 3/3/2011(from date - to date)
