BAPI_ITOB 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 "PM: BAPI Structure for ITOBAPI_CREATE + READ Fields" 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_BAPI_ITOB TYPE BAPI_ITOB.
The BAPI_ITOB table consists of various fields, each holding specific information or linking keys about PM: BAPI Structure for ITOBAPI_CREATE + READ Fields data available in SAP.
