FIELD_SELECTION_ATTRIBUTES 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 "Field Selection Attributes" 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_FIELD_SELECTION_ATTRIBUTES TYPE FIELD_SELECTION_ATTRIBUTES.
The FIELD_SELECTION_ATTRIBUTES table consists of various fields, each holding specific information or linking keys about Field Selection Attributes data available in SAP. These include IDENTIFIER (Field selection: Group of modified fields), INPUT_FLAG (Character length 1), REQUIRED_FLAG (Character length 1), OUTPUT_FLAG (Character length 1)... 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. .
