RSPLF_S_RANGE 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 "Range Structure (for Parameter and Condition)" 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_RSPLF_S_RANGE TYPE RSPLF_S_RANGE.
The RSPLF_S_RANGE table consists of various fields, each holding specific information or linking keys about Range Structure (for Parameter and Condition) data available in SAP. These include SELTP (Selection type), SIGN (SIGN field in creation of SELECT-OPTIONS tables), OPT (Operator in Select Options and other Expressions), LOW (Dim: Field for a User-Defined Characteristic Value)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
