FRMLS_API_MATRNG 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 Material" 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_MATRNG TYPE FRMLS_API_MATRNG.
The FRMLS_API_MATRNG table consists of various fields, each holding specific information or linking keys about RMS-FRM: API Value Range for Material data available in SAP. These include MATNR (Material Number of an Item), COMPTGT (Quantity of a Material or Substance Item), COMPTGT_ERR_FLG (Error When Converting Units), OPLOW (Operator for Lower Limit)...
