I am still not sure I follow. Are we talking MS Project 2007 or 2003?
In MS Project 2007, there are three "Cash Flow Reports:"
1) Report > Reports > Costs > Cash Flow
2) Report > Visual Reports > Cash Flow (Visio)
3) Report > Visual Reports > Cash Flow (Excel)
I suspect that we're talking about the last option. When I create that report,
the default view does not include tasks. When I drag them from the right
hand column to the table, it displays tasks with the project summary task,
and allows me to select the level at which I want to see the data. Further
moving the time element to the top, allows me to see all costs by tasks across
time, including the project summary task.
Is this what you're looking for?
