Hi

difference between call transaction and session method .

The most important aspects of the batch session interface are: - Asynchronous processing - Transfers data for multiple transactions - Synchronous database update During processing, no transaction is started until the previous transaction has been written to the database. - A batch input processing log is generated for each session - Sessions cannot be generated in parallel

The most important aspects of the CALL TRANSACTION USING interface are: - Synchronous processing - 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. - No batch input processing log is generated.

Here the differences betrween session and call transaction

session method

1) asynchronous process

2)synchronous update

3)multiple transactions can be handled (Menas u can upload the data at a time formore than one t-code)

4)huge amount of data can be uploaded.

5)implicit error handling (Menas for errors SM35)

6)execute the session on a specific date. (by using hold date parameter)

7) Time requirement is more

Call transaction:

1)asynchronous process

2)asynchronous /synchronous update

3) single transaction only handled

4)small amount of data uplaoded

5)explicit error handling (Menas all the error records move to internal table and validate)

6) Time requirement is low.
