I have looked all over and have not found my exact situation, so I am posting my first question. I have a report that I have grouped on multiple levels. So my report has a customer/header/detail/release grouping. I have written a custom
expression so that only a single value, which is the max value in the group, is shown in the detail, with all values showing in the release. I have then set my visibility toggle to toggle on header, then detail, then release and I need to sum up those
max values into a field on the report. The custom expression that I have written works correctly when you are showing on the detail level. It gives the correct value, which is the max value in each release.
What I then need the report to do is to sum only that max value and roll that up into the header group, so that I get a total of the max values.
I have tried using the MAX function in my expression to get the correct max value, but I cannot get SSRS 2008 R2 to sum that, and I have tried writing a custom expression that will calculate the max (Non-zero values divided by number of non-zero records) and both ways work correctly until I try to rollup and sum to the next group level.
I have also tried using a group variable and custom code to get the value and save it to a variable, but I have not had any luck in setting or getting that value correctly back to my report.
At its most basic it feels like I should be able to set a Sum(Max(Fields!ValueColumn.Value) and let SSRS handle how that should be broken out, but after trying that repeatedly I have still had no luck. I cannot adjust the SQL as I need the level of detail that the report shows, although I could add more fields as long as I don't add any groupings or totals that would reduce the granularity of that data being returned.
Any new avenue to explore would be very helpful.
Thank you in advance,
Chad
