SAP MAM_20_CLASSVALUES Evaluations for Characteristics Table data and field list

MAM_20_CLASSVALUES 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 "Evaluations for Characteristics" 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_MAM_20_CLASSVALUES TYPE MAM_20_CLASSVALUES.

The MAM_20_CLASSVALUES table consists of various fields, each holding specific information or linking keys about Evaluations for Characteristics data available in SAP.
