CONF_OBJK 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 "Confirmed object key (order/operation)" 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_CONF_OBJK TYPE CONF_OBJK.
The CONF_OBJK table consists of various fields, each holding specific information or linking keys about Confirmed object key (order/operation) data available in SAP. These include AUFNR (Order Number), APLFL (Sequence), VORNR (Operation/Activity Number), UVORN (Suboperation)... 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. .
