TFW_WHERE_USED_OBJ_STRUCT 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 "Object Structure for Where-Used PopUp" 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_TFW_WHERE_USED_OBJ_STRUCT TYPE TFW_WHERE_USED_OBJ_STRUCT.
The TFW_WHERE_USED_OBJ_STRUCT table consists of various fields, each holding specific information or linking keys about Object Structure for Where-Used PopUp data available in SAP. These include DISPLAY_IN_ALV (Boolean Variable (X=True, -=False, Space=Unknown)), FIELD_STRUCTURE (Name of Dictionary Type)...
