I am trying to develop a high level data flow diagram to map
out the intefaces between our applications. One of the
mechanisms we use is an XML "datagram" which is basically an
XML message published on a queue which is then used by
multiple consuming applications. I would like to have a
single flow defined with multiple targets, but PowerDesigner
only allows one target.

The only way I have been able to model this has been to put
in a split/merge showing the message coming in and several
messages going out. However, the impact of this approach is
that the "same" message is defined mulitple times. This
will make maintenance and impact analysis more difficult.

Does anyone have a suggestion on a better approach?
