Report service classes are in the data itself so they will be loaded directly from the Visualizer DB. Multiple report service classes can make up one application and we need to forecast by application. We use suites which come from data with different data sources and we have a table that groups them together. Suites come from the data within type 30 records which are event driven records. While report service classes come from type 72 which are time driven records (15 min intervals) which matches the rest of the data(this is where some of the confusion come in).
