CKI_NBV_ML 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 "Fields for subsequent debit -SALKV- (Clsg.ML)" 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_CKI_NBV_ML TYPE CKI_NBV_ML.
The CKI_NBV_ML table consists of various fields, each holding specific information or linking keys about Fields for subsequent debit -SALKV- (Clsg.ML) data available in SAP. These include SALKV_2 (Value based on the periodic unit price (only with pr.ctrl S)), SALKV_3 (Value based on the periodic unit price (only with pr.ctrl S))...
