BURS_RELATION_DATA 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 "Business Partner Relationship Data" 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_BURS_RELATION_DATA TYPE BURS_RELATION_DATA.
The BURS_RELATION_DATA table consists of various fields, each holding specific information or linking keys about Business Partner Relationship Data data available in SAP.
