FRMLS_API_SUBRNG 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 "RMS-FRM: API Value Range for Substance" 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_FRMLS_API_SUBRNG TYPE FRMLS_API_SUBRNG.
The FRMLS_API_SUBRNG table consists of various fields, each holding specific information or linking keys about RMS-FRM: API Value Range for Substance data available in SAP.
