AFFL_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 that are relevant for update from AFFL (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_AFFL_UPDATE_RELEVANT TYPE AFFL_UPDATE_RELEVANT.
The AFFL_UPDATE_RELEVANT table consists of various fields, each holding specific information or linking keys about Fields that are relevant for update from AFFL (sim. vers.) data available in SAP. These include PLNTY (Task List Type), PLNNR (Key for Task List Group), PLNAL (Group Counter), PLNFL (Sequence)... 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. .
