COMT_SELECTION_TABLE 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 "Transfer Structure for Dynamic Selection Parameters" 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_SELECTION_TABLE TYPE COMT_SELECTION_TABLE.
The COMT_SELECTION_TABLE table consists of various fields, each holding specific information or linking keys about Transfer Structure for Dynamic Selection Parameters data available in SAP.
