Hi guys,I have a transactions table and a lookup table.They're both connected by rate type.I wanna see how much is my revenue for a specific periode and rate, as well as the difference between the actual rate and the discount rate. I have that information on my lookup rate table. My question is, how to have all that accurate info, on a report?Once a relationship between both tables is created...1. I just pick the fields i want from both tables2. I do a merge between both tables and add all fileds to later pick the ones i want3. I can do a RELATE on my transactions table of the fields that i want.I believe all 3 options can work but i don't know which one garantees me accurate values and also, the option that allows faster calculations, cose so far this table is almost 100k records.Thank you all very very muchPedro

If you can do it, 2 should provide the fastest calculations because you would want to do that in the Query Editor so there is less work to be done calculating things during display. All 3 will work however. Sample data though would be very helpful to provide specifics.
