COMT_PRODUCTH 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 "Product History" 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_PRODUCTH TYPE COMT_PRODUCTH.
The COMT_PRODUCTH table consists of various fields, each holding specific information or linking keys about Product History data available in SAP. These include CLIENT (Client), PRODUCT_GUID (Internal Unique ID of Product), VALID_TO (Valid To (Time Stamp)), PRODUCT_ID (Product ID)... 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. .
