When you specify data for a grid, you set criteria that identifies the data to retrieve. You set the criteria by assigning members to the rows, columns, and page axes in the grid, as well as to the grid point of view (POV) and user POV bars. (See Defining the User POV.)
You can create lists of reusable members, and use functions to retrieve members dynamically. Before you define members, you must insert a grid in the report and define its dimension layout. (See Adding Grids.)
