In a report model I have some entities which have attributes which are integers (set to integer datatype) but should not be summed or aggregated in any way. For examples ID's. But when I create reports with the wizard, sometimes the report builder will try to sum the values even though it doesn't make sense to sum ID's. For example let's say I have a list of cars sold in a month. In january I've sold 2 cars, one with the ID 101 and one with the ID 210. In report builder I will then - when using the wizard - get the number 311 for the summed values. I can remove it afterwards, but I would like this to not happen at all (since the end-users will be confused)
I need a way to say to the report model: This is an integer, but it is not really a number you should sum up
Well the wizard isn't perfect as you've found out. It does it's best in trying to figure out what to do. All that you can really do is remove =Sum(carID.value, "datasetname") when it automatically puts it there. Or if you don't need to sum anything at all delete the footer of the table. A workaround perhaps would be to do a Convert in your SQL to make your ID's a varchar.
