hi,

Session method.

1) synchronous processing.

2) can tranfer large amount of data.

3) processing is slower.

4) error log is created

5) data is not updated until session is processed.

Call transaction.

1) asynchronous processing

2) can transfer small amount of data

3) processing is faster.

4) errors need to be handled explicitly

5) data is updated automatically

Session method is to populate the data by filling BDC structure

and keep as session to process from SM37 to post in appropriate Transaction.

Call transaction method is to post the data directly into the Transaction from an Executable program.

Session method SAP defined Function modules.

U can see more help on the differences in the SAP help.
