COMT_CUVK 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 "Variant Condition Keys in a Configuration" 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_CUVK TYPE COMT_CUVK.
The COMT_CUVK table consists of various fields, each holding specific information or linking keys about Variant Condition Keys in a Configuration data available in SAP. These include CONFIG_ID (External Configuration ID (Temporary)), INST_ID (Instance Number in Configuration), VKEY (Variant Condition Name), FACTOR (Weighting Factor for Variant Conditions)... 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. .
