I suppose I multipass report is one that builds the report in passes.
Say you add a summary field in a footer band. Well that value is not available until
the band has printed. Now suppose you want to know the % of the row just printed
against the summary value. Well you would need to calculate the total and then you
calculate the % for the row.
Say you have this
10/5/90 Chris Crowe $100.00
10/5/90 Test Case $200.00
10/5/90 John Smith $100.00
===========================================
3 $400.00
But you really want this
10/5/90 Chris Crowe $100.00 25%
10/5/90 Test Case $200.00 50%
10/5/90 John Smith $100.00 25%
===================================================
3 $400.00 100%
I do not think you can do this without a multipass report generator. Since the total
400 needs to be known at the time the first line is generated.
I suppose you also could use it when you need to know the total number of pages so you
can use "Page 1 of 45" etc...
I could be wrong, but this is what I think it means.
