Why state records are needed?
State records are used in Application engine development and customization. Basically they are used to pass the values(variables, database field) from from section to another section, from action to another action.Each application engine can have multiple state record but there will be only one default state record. It can be a SQL table or derived table. All state record ends with _AET.
The use of State record beside just passing the parameters between different steps of AE, is to enable restart logic. The programmer can program AE by using state record, in such a way that it can be restarted from any point of AE. But to enable the restart, the state record should be physical table and not the derived/work record.
