Grid History
If the grid history is activated you can display information on when the grid was changed, who changed it, and what was changed.
You can make changes to a grid if you have not yet used it, for example, combine additional grid values or cancel existing combinations. You can also add dimension values to master grids.
Once you have used a grid, you cannot change settings for dimensions or grid values, but you can add new dimension values and combine other grid values.
If you activate the grid history in Customizing and in the grid, the system logs all changes. You can query the changes any time using reports.
Under Grid Number Ranges and Grid History in Customizing, you decide whether you want to use the function in your system and whether it should be active for all grid types or certain types only.
The grid history is activated for all grid types in standard Customizing.
If you keep the default settings in Customizing, you can specify whether or not you want the system to record changes when you create or enter a grid.
