VTB_DFREQ 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 "Datafeed: Structure for Querying 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_VTB_DFREQ TYPE VTB_DFREQ.
The VTB_DFREQ table consists of various fields, each holding specific information or linking keys about Datafeed: Structure for Querying Values data available in SAP. These include RINID1 (Datafeed: Instrument name), RINID2 (Datafeed: Data source), SPRPTY (Market data: Instrument property), DFROMDATE (Datafeed: Value date in SAP format)...
