FMDPEF_DOC_LINE 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 "DP with EF reference doc line" 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_FMDPEF_DOC_LINE TYPE FMDPEF_DOC_LINE.
The FMDPEF_DOC_LINE table consists of various fields, each holding specific information or linking keys about DP with EF reference doc line data available in SAP. These include WRBTR (Amount in document currency), DMBTR (Amount in Local Currency), FLG_OK (Booking Ok), KBLNR (Document Number for Earmarked Funds)... 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. .
