CN10_TOOL is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "CN33: Analysis tool" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_CN10_TOOL TYPE CN10_TOOL.
The CN10_TOOL table consists of various fields, each holding specific information or linking keys about CN33: Analysis tool data available in SAP.
