Grouping rows or columns

For many analyses or summaries, the categories have to be grouped. You can merge the results in classes or periods. In the DataPilot you do a grouping after you have first made an ungrouped DataPilot table.

You can access the grouping with the menu entry Data > Group and Outline > Group or by pressing F12. It is important that you select the correct cell area. The grouping function is mostly dominated by the kind of values that have to be grouped. You have to distinguish if you have scalar values, date or time values or other values like text that you want to group.

Image:documentation_note.png The time needed for creating a DataPilot depends mostly on the number of columns and rows (and not of the size of the basic data). Through grouping you can produce the DataPilot with a small number of rows and columns. Before you can group you have to produce a DataPilot with ungrouped data as an intermediate step. This DataPilot can contain a lot of categories, depending on your data source. Please expect in such cases a computing time of several minutes!
