FVVDBOHEAD 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 "Change Document Structure" 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_FVVDBOHEAD TYPE FVVDBOHEAD.
The FVVDBOHEAD table consists of various fields, each holding specific information or linking keys about Change Document Structure data available in SAP. These include MANDT (Client), BUKRS (Company Code), SARCHIV (Archiving Category Indicator), RANL (Contract Number)... 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. .
