Posting Date Variable

Hi All,

I have a requirement.  I need to be able to select a Posting Date Variable (Single Value) at the selection screen to collect all posting values from the beginning of the year regardless of which month and day selected.  Example:  If I select October 20 2014, I want all posting values that has occurred from January 2014 to date (October 20 2014.  Likewise, if I select March 10 2014, I want all posting values that has occurred from January 2014 to date (March 10 2014).

Thanks,

Recca
