RSPLFU_S_VARIABLE 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 Variables" 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_RSPLFU_S_VARIABLE TYPE RSPLFU_S_VARIABLE.
The RSPLFU_S_VARIABLE table consists of various fields, each holding specific information or linking keys about Structure for Variables data available in SAP. These include VNAM (Name (ID) of a Report Variable), TEXT (Long description), VARTYP (Type of a Report Variable), VPARSEL (Parameter Selection: Single Value, Interval, Selection Opt.)...
