Creating a date range parameter on SSRS report in AX 2012

Hi,

I'm brand new to the forum and to Dynamics AX 2012 report development, and have a question around ranges and parameters.

I've built a new query in the AOT, dragged tables into, and defined the relationships.  I've made a test report and precision design in Visual Studio 2010 and the query pulls the data I expected and displays it appropriately.  Now, I am looking to add the ability for the user to enter a date range to run the report for.

I've tried adding a column to my query as a range.  The column is called startDateTime and is data type DateTime.  I refresh my data set in VS, and it appears as a parameter under both the data set, as well as the report.  By default, it is giving me the option to enter a single DateTime value which appears to be added to the query as a constraint.

However, I want the user to enter a date range, preferably without entering times.  For example, 01-SEP-2014 to 30-SEP-2014.  I haven't found any way to change the data type to strip the time off, nor have I found a way to choose a date range instead of a single date.

I did try using the "dot-dot" syntax:  9/1/2014..9/30/2014 and I received an error. Trying it with time attached doesn't work either.

Can anyone provide advice on the proper way to accomplish this?

Thanks much.

Tony
