FMABP_DATA 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 "Automatic Budget Posting 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_FMABP_DATA TYPE FMABP_DATA.
The FMABP_DATA table consists of various fields, each holding specific information or linking keys about Automatic Budget Posting Data data available in SAP. These include SENDER_DATA (Automatic Budget Posting Sender Data Indicator), RLDNR (Ledger), WRTTP (Value Type), VRGNG (CO Business Transaction)...
