COMT_IFVAL_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 "Interface CFG: Configuration Values" 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_IFVAL_MD TYPE COMT_IFVAL_MD.
The COMT_IFVAL_MD table consists of various fields, each holding specific information or linking keys about Interface CFG: Configuration Values data available in SAP.
