CMS_STR_BP_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 Details (From External 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_CMS_STR_BP_DATA TYPE CMS_STR_BP_DATA.
The CMS_STR_BP_DATA table consists of various fields, each holding specific information or linking keys about Business Partner Details (From External System) data available in SAP.
