BBPS_DIFF_INT 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 "Internal Fields for Document Comparison" 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_DIFF_INT TYPE BBPS_DIFF_INT.
The BBPS_DIFF_INT table consists of various fields, each holding specific information or linking keys about Internal Fields for Document Comparison data available in SAP. These include GUID1 (Globally Unique identifier), GUID2 (Globally Unique identifier), OBJECT_KIND (Object Type), OBJECT_NAME (Business Transaction Subobject)... 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. .
