PSJ_AUTH 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 "Authorizations for objects selected in LDB PSJ" 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_PSJ_AUTH TYPE PSJ_AUTH.
The PSJ_AUTH table consists of various fields, each holding specific information or linking keys about Authorizations for objects selected in LDB PSJ data available in SAP. These include OBTYP (Object Category), DISPLAY (Ind.: Authorization exists), TIMEDISP (Ind.: Authorization exists), COSTDISP (Ind.: Authorization exists)... 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. .
