Grids are tables that contain data from external database connections.
You can add a grid to your report, define its dimension layout, select members, and then format the grid. You can use text, dimensions, members, and formulas to define the grid content. You can hide a grid from being displayed in the report output. For example, if you use row or column formulas to pull in data from additional data sources into one grid, you can hide the source data grids by placing them in the hidden sheet.
