Maintain Libraries
In this IMG activity, you can maintain previously defined libraries or create new ones. You must assign each report that you define to a library.
A library is a selection of characteristics, key figures, and predefined columns from the list of all options in the Report Writer table. In Controlling, table CCSS is used.
- A characteristic (in earlier releases field or dimension) is a non-numerical field, for example, Account, Cost center, and Business area .
- A key figure (new as of Release 3.0) is a numerical value field, such as Amount in local currency , Total costs, and Activity quantity.
- A default column (in earlier releases Data-set-entry is made up of a key figure and one or more characteristics. With default columns, you can define standard columns that can be used more than once in your reports, for example, Actual costs in current fiscal year and Plan costs in closed fiscal year .
Four screens are available for library maintenance:
- Header
- Key figures
- Characteristics
- Default columns

For steps 2 to 4, if necessary, enter the ranking order (position) in which the characteristics, default columns, and key figures are to appear in the selection lists of the Report Painter.
