BBPS_CTR_UI_DEFAULT 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 "Default Values for Purchase Contract" 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_BBPS_CTR_UI_DEFAULT TYPE BBPS_CTR_UI_DEFAULT.
The BBPS_CTR_UI_DEFAULT table consists of various fields, each holding specific information or linking keys about Default Values for Purchase Contract data available in SAP. These include PROC_GROUP (Responsible Purchasing Group), CURRENCY (Currency Key), CATALOGID (Catalog ID from which the line was selected), SUBTYPE (Specification of a Purchasing Doc.(e.g. Credit Memo/Invoice))...
