RDDEFDATESCF 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 "Default: Date Fields for Cash Flow" 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_RDDEFDATESCF TYPE RDDEFDATESCF.
The RDDEFDATESCF table consists of various fields, each holding specific information or linking keys about Default: Date Fields for Cash Flow data available in SAP. These include NEXT_PDUED (Next Payment Due Date), NEXT_SCHP (Next Scheduled Payment (Date)), DLASTP (Last Payment), DLASTBILL (Field of type DATS)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
