What Is The Biggest Disadvantage Of Using Batch Input Session Method?

Session Method Disadvantage in SAP ABAP.

When dealing with batch input sessions, there is a timing issue involving the creation of a batch input session and the processing of a batch input session. The creation and processing of batch input sessions are distinct or two different actions; therefore, they occur at different times.

Between the time a batch input session is created and the time it is processed, changes might have been made to the SAP database. These changes may result in errors when processing the batch input session.

For example, a BDC program creates a batch input session to insert 10000 materials into the SAP database. Before the session is processed, a SAP user inserts 20 of these materials into the SAP system. When the batch input session is finally processed, these 20 materials will result in errors because they cannot be inserted into the SAP database more than once. Also Batch Input Sessions cannot be run in parallel and hence are not fast.
