For state record...

State record is used for providing the variables database fields to different sections of the application engine. Scope of the state record is limited to the application engine program. AE can have multiple state records but can have only one as a default state record.

It can be physical or derived work record. Physical record can be used when you have a restart logic and when you have disables the restart logic derived and work record can be used.

The naming convention is it must end with _AET identifier and process instance should be the one and the only key for the state record so that application will identify the record as a state record.

Temporary table: To allow other users to access the same table that has been using by the AE program. These are mainly used in batch processing. These can store specific data to update without affecting the main application table. This is a database object. To increase the performance of AE program. Used to process data of tables having huge amounts of data in less time.

State record: We can use to pass variables between sections to section. Process instance is the mandatory field. We can insert the data into state record through select selectinit. We can retrieve the data from the state record through bind. The name of the state record must end with AET. When the AE program completes successfully the row of data in the state record is deleted.
