BUS0CHDOC 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 "CBP: Work structure for change documents; event: CHDOC" 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_BUS0CHDOC TYPE BUS0CHDOC.
The BUS0CHDOC table consists of various fields, each holding specific information or linking keys about CBP: Work structure for change documents; event: CHDOC data available in SAP. These include KEYNAM (CBP: Name of Key Field), KEYVAL (Central business partner: Formatted table key string), TABBEZ (CBP: Name of table), OBJBEZ (CBP: Name of change document object)... 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. .
