SRULES_EXT 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 "Create settlement rule, reference added for CO-PA data" 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_SRULES_EXT TYPE SRULES_EXT.
The SRULES_EXT table consists of various fields, each holding specific information or linking keys about Create settlement rule, reference added for CO-PA data data available in SAP.
