BAPI_INSOBJECT_KEY_BCON 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 "Reference to the Contract in the Feeder System" 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_INSOBJECT_KEY_BCON TYPE BAPI_INSOBJECT_KEY_BCON.
The BAPI_INSOBJECT_KEY_BCON table consists of various fields, each holding specific information or linking keys about Reference to the Contract in the Feeder System data available in SAP. These include BASECONTRACT_ID (Contract ID in the Feeder System), BASECONTRACT_ITEM_TYPE (Contract Subtype in the Feeder System), BASECONTRACT_ITEM_ID (Contract Subidentification in the Feeder System), BASECONTRACT_BUSINESS_SYSTEM (Feeder System for the Contract)...
