On a summary report, one customer has a total of 50.000 invoiced and 25.000 paid, whereas the details report reports only 2 invoices (one of 10k and the other of 15k), both without payments.
So the total is the same, and it doesn't show the payments, right?
I may have fixed this but can't confirm without more info. Could you try again on the tip of branches/1.3?
The totals differ: the details report shows all invoices (ie 50k, including fully paid ones) while the details report shows a total of 25k (ie all which have a "to pay" amount).
The total remaining amount is the same in both reports though.
Tried with trunk from "now": no change in behaviour.
Outstanding details report
Outstanding summary report (same date, same open invoices)
Uploaded screenshots to show what I mean.
This was duplicated by a later bug ticket which has more information including an assessment of impact and root cause.
