RFICOS_RUNTIME 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 "Structure for Specification of Term" 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_RFICOS_RUNTIME TYPE RFICOS_RUNTIME.
The RFICOS_RUNTIME table consists of various fields, each holding specific information or linking keys about Structure for Specification of Term data available in SAP. These include MIN_OVERALL_RUNTIME (Overall Term)...
