Also we would like to know if you would be running the report once a day, week , month? It seems to me that at any point you execute the report you would like to see the aggregates for that day, that week and that month for the given agent. In theory it looks like you need three record sets, one for each aggregation, and then join them together by the agent ID. You need to start with a Calendar table. Please follow the advise of the previous posts so you can be better guided.
