EV03V_I 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 "Include structure for quantity block" 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_EV03V_I TYPE EV03V_I.
The EV03V_I table consists of various fields, each holding specific information or linking keys about Include structure for quantity block data available in SAP. These include MATNR (Material Number), WERKS (Plant), DELKZ (MRP element), MBDAT (Material Staging/Availability Date)...
