COMS_ALTID_TYPE 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 "Control Data for Alternative Product IDs" 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_COMS_ALTID_TYPE TYPE COMS_ALTID_TYPE.
The COMS_ALTID_TYPE table consists of various fields, each holding specific information or linking keys about Control Data for Alternative Product IDs data available in SAP. These include OBJECT_TYPE (Object Type for Alternative IDs), ID_TYPE (ID Type for Alternative IDs), CLASS_NAME (ABAP Class Name for Alternative IDs), MAIN_FIELD (Table Field Name for Alternative IDs)... 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. .
