AVSELECT_3 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 "Data basis selection" 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_AVSELECT_3 TYPE AVSELECT_3.
The AVSELECT_3 table consists of various fields, each holding specific information or linking keys about Data basis selection data available in SAP. These include ALLGDBASE (Flag, general data basis), LASTUPDATE (Date), AVNAME (Name of an existing work list), GEN_FLG (Single-Character Indicator)... 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. .
