SAP API_NESTED Structure for 'Nested KMAT' Table data and field list

API_NESTED 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 "Structure for 'Nested KMAT'" 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_API_NESTED TYPE API_NESTED.

The API_NESTED table consists of various fields, each holding specific information or linking keys about Structure for 'Nested KMAT' data available in SAP. These include PARENT (Configuration (internal object number)), SELF (Configuration (internal object number)), OBTAB (Name of database table for object), OBJEK (Key of Object to be Classified)...
