COMT_PROD_VAR_DATA 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 "Data on Product Variant or Configurable Product" 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_PROD_VAR_DATA TYPE COMT_PROD_VAR_DATA.
The COMT_PROD_VAR_DATA table consists of various fields, each holding specific information or linking keys about Data on Product Variant or Configurable Product data available in SAP. These include CUOBJ (Configuration (Internal Object Number)), COMM_PROD_VAR (Dummy function in length 1)... 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. .
