Suppose I am loaded with questions as I am an experienced etl coder, but not an analytical report builder. I am using analysis services to build a cube but am trying to choose the reporting architecture. Can someone please confirm whether or not reporting services (using the business intelligence report) will allow for slicing and dicing, or is it only a static report builder. Also, if I am using the cube browser in analysis services, where can I put the option of non empty so that I dont see records that are blank.?
