You're Welcome Eric.
Yes you're right, The HL7 based BS is quite powerful and can do many
things for us like sending an Immediate ACK.
The Suggestion about calling a simple BP
was so that you could further demo the Arrival of the HL7 Message and
show your audience -visually,
that indeed the message you sent, arrived on the other side...
You can view the message info in
[Ensemble] > [Event Log]
or
even better in
[Ensemble] > [Messages] > [Visual Trace]
otherwise you just see the ACK on the calling system.. which I guess
it's OK too :-)
All the best
