So im creating a matrix that returns all of the previous year of data plus this year so far up to the previous month. So if ran today it would return data from January 2009 to November 2010. What im curious about is if there is a way to hide columns based on a date. So i only want to see the past year of data. Now im sure you would immideately say change the query or stored proc, but its necessary to have that data there because of other columns that will be added on later to the report that require the entire previous year. So right now i just want to hide those first few columns so only the previous year shows.
