COMT_CUINS_DATA_MD 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 "Instances in a Configuration Data" 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_COMT_CUINS_DATA_MD TYPE COMT_CUINS_DATA_MD.
The COMT_CUINS_DATA_MD table consists of various fields, each holding specific information or linking keys about Instances in a Configuration Data data available in SAP.
