COMT_FRAGMENT_CHANGES 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 "Changed Sets" 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_FRAGMENT_CHANGES TYPE COMT_FRAGMENT_CHANGES.
The COMT_FRAGMENT_CHANGES table consists of various fields, each holding specific information or linking keys about Changed Sets data available in SAP. These include FRAGMENT_GUID (Set GUID), UPDATE_TYPE (Type of Change)... 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. .
