VTBDFET 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: Excluding parameter structure for GUI status" 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_VTBDFET TYPE VTBDFET.
The VTBDFET table consists of various fields, each holding specific information or linking keys about Datafeed: Excluding parameter structure for GUI status data available in SAP. These include FCODE (Not More Closely Defined Area, Possibly Used for Patchlevels)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
