COMT_IPRODUCT 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 "General Product 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_IPRODUCT TYPE COMT_IPRODUCT.
The COMT_IPRODUCT table consists of various fields, each holding specific information or linking keys about General Product Data data available in SAP. These include CLIENT (Client), PRODUCT_GUID (Internal Unique ID of Product), PRODUCT_ID (Product ID), PRODUCT_TYPE (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. .
