AFAB_UPDATE_RELEVANT 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 "Fields relevant to update from AFAB (sim. vers.)" 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_AFAB_UPDATE_RELEVANT TYPE AFAB_UPDATE_RELEVANT.
The AFAB_UPDATE_RELEVANT table consists of various fields, each holding specific information or linking keys about Fields relevant to update from AFAB (sim. vers.) data available in SAP. These include AOBAR (Type of relationship), MIMAX (Indicates whether maximum time interval will be considered), ZEINH (Unit for the time interval between relationships), DAUER (Time interval between relationships)... 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. .
