COMT_HIERARCHY_SCHEMA 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 "Schema Hierarchy" 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_HIERARCHY_SCHEMA TYPE COMT_HIERARCHY_SCHEMA.
The COMT_HIERARCHY_SCHEMA table consists of various fields, each holding specific information or linking keys about Schema Hierarchy data available in SAP. These include TEXT (), SCHEMA_TYPE (Standard Schema Type), LOGSYS (Original System), CONF_HIER_PRTYPE (Product Type)... 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. .
