RCHARGE_STEER_UI 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 "User Interface Control Data for Charges" 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_RCHARGE_STEER_UI TYPE RCHARGE_STEER_UI.
The RCHARGE_STEER_UI table consists of various fields, each holding specific information or linking keys about User Interface Control Data for Charges data available in SAP.
