Report Parameter Default Values

While developing SSRS reports I almost always define default report parameters in case I need to fix some issue with layout or data itself. It saves some time as I don't have to fill report parameters each time I want to preview report with new changes applied.
But after report is deployed to production report server and users start using it default parameters are not that handy there. Especially with heavy statistics reports (that takes more than several seconds to process request) when report engine starts processing request at once using default parameters. Almost in all cases default parameters does not match user's. Nobody wants to wait extra before submitting desired input parameters especially when "extra" is several minutes long.


So don't forget to empty default parameters prior to deploying report or if deployed empty them and redeploy.

PS: And don't forget to update report subscriptions as well in case you have some.
