COMT_SETTYPE_16 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 "Set Type Header Data" 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_COMT_SETTYPE_16 TYPE COMT_SETTYPE_16.
The COMT_SETTYPE_16 table consists of various fields, each holding specific information or linking keys about Set Type Header Data data available in SAP. These include SETTYPE_GUID (Internal Key of a Set Type), BUS_OBJTYPE (Object Type of a Set Type), SETTYPE_TEXT (Set Type Description)... 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. .
