SAP GRFN_S_EXT_DATA Extension Data Table data and field list

GRFN_S_EXT_DATA 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 "Extension 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_GRFN_S_EXT_DATA TYPE GRFN_S_EXT_DATA.
