GRAC_S_APPLICATION_EXT 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 "Requested role information" 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_GRAC_S_APPLICATION_EXT TYPE GRAC_S_APPLICATION_EXT.
The GRAC_S_APPLICATION_EXT table consists of various fields, each holding specific information or linking keys about Requested role information data available in SAP. These include VALID_FROM (Validity Start Date), VALID_TO (Validity End Date), ACTION (Action ID), COMMENTS (Request Justification)...
