If the volume of data is high go for SESSION otherwisw use call transaction.

Hi,

You can decide based on the data volume that your BDC is processing. If data volume is high go for session else call transaction will do.The call transaction updates will be instantaneous where as session needs to be processed explictly after creation.

you can do it both manually and by using program RSBDCSUB.

Hope this helps.

Hi

A good practice is to use call transaction but use BDC session for when there is an error in the record.

i.e call transaction..

if sy-subrc ne 0.

perform form_bdc_session.

endif.

This method is quicker, you can capture errors and deal with them in a BDC session later.

Hope this helps.

Volume of data also needs to be checked.

hi Geetha,

First use the CALL TRANSACTION. If it errors out then use the BDC session method so that user can execute it online and rectify the errors.
