Building: Im trying to build a report where I can calculate the difference between two dates (Example between 1-1-2001 and 31-12-2001) but also showing (per name per identifier) the current balance of a customer per date(As shown in the Report attachment).
Problem: The problem is that the totals are not correct, they get multiplied on random numbers (Checking it with Count and CountDistinct I learned that I probably made a mistake in my SQL, so I copied SQL in this question as well).
I have tried plenty myself and tried to find solutions on the interwebs, but none of them seem to work. So I am desperate enough to ask for help :).
