Cross tab Summation in RTF
Crosstab report. It can be done in many ways, ideally people love to take some granular level data and manipulate and apply that in different template. Advantage of granular level data : We can use it for some other RTF template. We can show that the way we need to. If you pre-group, then your report will be faster. But you use the flex of using the same data for showing it different layout. since you pre-grouped it, its fixed data for some layout. You use this flex here. its a trade off on flex or performance, i choose go on the balanced line of these two. Forums thread with issue 1. it should be pretty simple in BIP template too. 2. have a look the thread link , i answered how to do it in Datatemplate. 3. Db rollup is also good option but for the answer at OPTION 1 look at this picture.
