RINTER_ADD_HEADER 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 "Additional Fields: Contract Data Header" 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_RINTER_ADD_HEADER TYPE RINTER_ADD_HEADER.
The RINTER_ADD_HEADER table consists of various fields, each holding specific information or linking keys about Additional Fields: Contract Data Header data available in SAP. These include INDICATOR_REQUIRED (Credit Life Insurance Mandatory), MMAXNORISKMS (Number of Risk-Increasing Measures), MNUMRTS (Number of Payment Installments in the Deferral Plan), SUNTGRN (Document Groups for Status)... 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. .
