Kelly,
call transaction is more efficient because to runs faster than BDC. However, BDC has a few advantages, for example you have the session available for analysis before you process it, you have a log available, etc.
The method you choose is entirely up to you.
Hi Kelly,
I see that you posted this query twice. Your previous one is still open. Could you please close one or both if your question is answered.
Thanks,
Srinivas
