This one of the less useful modules in dba.

That being said, it is valuable. We format it to use the entire range of GL Codes. This means that the entire report should net to zero. That is useful, as otherwise you don't know what has been left out.
We certainly don't have all columns be zero, particularly when using a difference. I wonder if you have set up the defaults correctly?
The main thing this does is let you know what catagories are varying in any one given month. This is an esoteric report. Useful only if you run it every month and become familiar with its quirks. To get the kind of date to date cash flow you are asking for, I think you will need to use Access and ODBC.
Good Luck.
