Hi Surya,

Processing means how the records will be processed in the database. In synchronous processing the records will be updated in the database table as soon as one record is updated. Then processing of next record will start .But in the Asynchronous processing one record will be processed , then it may happen that processing of second record will start prior to the updation of first record.

Thanks,

Aditya.

In batch session interface: - Asynchronous processing means Transfers data for multiple transactions - Synchronous database update means during processing, no transaction is started until the previous transaction has been written to the database.

In CALL TRANSACTION: - Synchronous processing means Transfers data for a single transaction. Synchronous and asynchronous database updating both possible The program specifies which kind of updating is desired. Separate LUW for the transaction The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
