FMFEE_FEES 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 "Fee documents" 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_FMFEE_FEES TYPE FMFEE_FEES.
The FMFEE_FEES table consists of various fields, each holding specific information or linking keys about Fee documents data available in SAP. These include BELNR (Accounting Document Number), BUZEI (Number of Line Item Within Accounting Document), BLART (Document Type), KUNNR (Customer Numbers)... 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. .
