SIMAPARPAY_DATA_DI 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 "IO: DI: Outgoing Payment 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_SIMAPARPAY_DATA_DI TYPE SIMAPARPAY_DATA_DI.
The SIMAPARPAY_DATA_DI table consists of various fields, each holding specific information or linking keys about IO: DI: Outgoing Payment Data data available in SAP. These include ORD_OP (Classification Key), ABWRA_OP_X (Alternative Payee), ADRRA_OP_X (Address Number for Alternative Payee), ABVTY_OP_X (Bank Details ID for Outgoing Payments)...
