Hi,

I think insertion point is when you execute the BDC in session method which you use 2 FMs BDC_INSERT and BDC_CLOSE. Hence there can be only one point in a program.

Thanks..

in BDC the data is inserted when you call respective transaction. (If BDC is created for transaction)

for session BDC data is inserted when you execute perticular session created when BDC was executed.

In BDC data can be migrated using call transaction or session method.

What is the difference between batch input and call transaction in BDC?

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

Differences between bdc session method and call transaction 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.
