Hi All,
In the report builder 3.0, I have created a report which have 4 parameters, start date, end date, zone and building, and I want to allow zone and building not to be selected hence send a blank or null to the query in background.
The question is I have ticked "allow to use blank", "allow to null" and I set the default value for the parameter to 'null', in the query area it looks like (zone = @zone or @zone is null) and (building = @building or @building is null), then run the report, I select a start date and end date, leave others as default: " select a value", then it doesn't allow to run report, it just pops up a window says "please select a value for parameter 'xxx' "... any ideas???
Thanks in advance,
Albert
