BDICSLTKEY 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 "Delivery Structure: CSLT Key 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_BDICSLTKEY TYPE BDICSLTKEY.
The BDICSLTKEY table consists of various fields, each holding specific information or linking keys about Delivery Structure: CSLT Key Fields data available in SAP.
