E2KNVPM 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 "Master customer master partner roles (KNVP)" 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_E2KNVPM TYPE E2KNVPM.
The E2KNVPM table consists of various fields, each holding specific information or linking keys about Master customer master partner roles (KNVP) data available in SAP. These include PARVW (Partner Function), KUNN2 (Customer number of business partner), DEFPA (Default Partner)... 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. .
