BAPILOAN_USERFIELDS 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 "User Fields" 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_BAPILOAN_USERFIELDS TYPE BAPILOAN_USERFIELDS.
The BAPILOAN_USERFIELDS table consists of various fields, each holding specific information or linking keys about User Fields data available in SAP. These include CONTRACT_NO (Contract Number), INT_NO (Collateral reference number), OBJECT_NO (Collateral object number), NO_RANGE (Key for number range object)... 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. .
