Thanks for the response.
One more question if i have to backfill the data for all the months, so i am creating subreport for each month i.e.
Jan till Dec
Jan count(event_id) for that month
Feb count(event_id) for that month
Mar count(event_id) for that month
Apr count(event_id) for that month
MAy count(event_id) for that month
June count(event_id) for that month
July count(event_id) for that month
Aug count(event_id) for that month
sep count(event_id) for that month
oct count(event_id) for that month
Nov count(event_id) for that month
Dec count(event_id) for that month
So when linking the main report with all the subreports shall i need to link each month subreport or just leave all of them non linked? Because i dont want the same clientcode and group parameters repeating 12 times when the client runs the report.
Any advice?
