VTSKAU_DEF 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 "Default Display Options for Bank Statement" 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_VTSKAU_DEF TYPE VTSKAU_DEF.
The VTSKAU_DEF table consists of various fields, each holding specific information or linking keys about Default Display Options for Bank Statement data available in SAP. These include DATE_TO (Field of type DATS), OPIT_VARIANT (Layout), POST_VARIANT (Layout), XOPIT_SHOW (Checkbox)...
