BBPS_SRC_DET 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 "Sourcing for Product Category" 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_SRC_DET TYPE BBPS_SRC_DET.
The BBPS_SRC_DET table consists of various fields, each holding specific information or linking keys about Sourcing for Product Category data available in SAP. These include ITEM_GUID (GUID of a CRM Order Object), VENDOR_ID (Supplier), VENDOR_NO (Partner Number), CONTRACT_ID (Transaction Number)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
