DIA_PERMIT 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 "Dialog structure for permits" 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_DIA_PERMIT TYPE DIA_PERMIT.
The DIA_PERMIT table consists of various fields, each holding specific information or linking keys about Dialog structure for permits data available in SAP. These include MANDT (Client), SOGEN (Permit Key), GNTYP (Permit Category), KZLTX (Long Text for Permit)... 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. .
