RIOA_FTGROUPS_SUM 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 "Interest on Arrears: Total per Flow Type Grouping" 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_RIOA_FTGROUPS_SUM TYPE RIOA_FTGROUPS_SUM.
The RIOA_FTGROUPS_SUM table consists of various fields, each holding specific information or linking keys about Interest on Arrears: Total per Flow Type Grouping data available in SAP.
