Question

Suppose one lack records having in BDC uplaod,which one can i propose uploading these records?call transaction or session method which one is better?How?

Answer 1

Hi Hassan,
The Session method is better and used for processing large amount of data and it will give error log itself if any comes. and the other thing is you can run session method in background but call transaction is not possible to run in background.
Session method can handle multiple transactions at a time, while in call transaction , only one at a time.
But call transaction is much faster than Session.
Database update is synchronous in Session,while it is either synchronous or asynchronous in Call Transaction.
here is the exact differences..
Call transaction:
Session is used to handle larger amount of data and error handling in implicit, while in call transaction, you have to explicitly handle error situation.
1.Synchronous Processing
2.You can update the database both synchronously and asynchrounously.
3.Transfer of data for individual transaction
4.No batch input session is created.
5.Faster than other batch input techniques.
6.No automatic error log and restart capability is available here.
7.Not recommended for bulk data transfer
Session.
1.Asynchronous Processing
2.Synchronous database updates
3.Transfer of data for multiple transaction
4.Batch input sesssion is created here.
5.Automatic error handling and efficient restart capability incase of error transaction.
6.SAP's standard approach for data transfer
7.Highly recommended for Bulk data transfer.
8.Execution is slower than CALL TRANSACTION.
