I have a matrix report (2008) containing about 30 columns and 200,000 rows. I came accross an article on how to populate the data on multiple worksheets. http://msdn2.microsoft.com/en-us/library/ms157328.aspx It requires that you set a group with a grup expression on X number of rows, then you page break on the group. The problem is that I don't understand how to do this using a Matrix. There are so many groups already, I don't know where to insert the new group. Is this even possible on a Matrix?
