Creating Report Titles
Because you cannot insert variables into a tabular layout, you cannot generate report titles automatically, as you would using a matrix layout. To create a report title in a tabular layout, insert a second sheet into your Excel workbook and create a matrix layout. Use the %RTT% variable to create the report title in the matrix layout, and then do an intra-sheet reference in Excel; the report title appears on your tabular report.
