Hi there, I have data that looks like this: AnimalClassAnimalQtyClassQtyDogMammal5080CatMammal3080ParrotBird2030HummingbirdBird1030So basically ClassQty is calculated in the database as a window function over the Class filed. I have the data above in the detail band of my report, and would like to have the animal class totals at the end of the report (I tried the summary band), such as: ClassClassQtyMammal80Bird30However, the naive approach of just placing the fields in the Summary band does not work, as I get a single row for the animal class of the last row in the detail band: ClassClassQtyBird30I tried to fiddle with evaluation time properties, but to no avail. I figure that I could just stick a subreport and be done with it, but I wonder if there is a cleaner solution that I might be overlooking.
