BUS_ROLE 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 "Role Category with Differentiation Type Value" 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_BUS_ROLE TYPE BUS_ROLE.
The BUS_ROLE table consists of various fields, each holding specific information or linking keys about Role Category with Differentiation Type Value data available in SAP. These include DFVAL (BP: Differentiation type value)... 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. .
