DIEQUI 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 "Equipment" 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_DIEQUI TYPE DIEQUI.
The DIEQUI table consists of various fields, each holding specific information or linking keys about Equipment data available in SAP. These include EQUNR (Equipment Number), ERDAT (Date on Which Record Was Created), ERNAM (Name of Person who Created the Object), EQASP (Language in Which the Piece of Equipment was Entered)... 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. .
