I was recently asked a few questions on how to do aggregate functions using Reporting Services (Reporting Services Documentation). While answering these questions I have had a chance to really dig into the report designer and am much more comfortable and excited about what you can do. I'm hoping to put some examples online that I have done on how to do certain things, but in the meantime I will try to at least put the questions I get asked here. Also, if you have questions feel free to leave them in the feedback and I will do my best to get you the most accurate answer, or redirect you to somewhere that has the answer already.
