I have an AS2/EDI solution where my trading partner wants me to use a single AS2 identifier for multiple site locations, using both X12  and EDIFACT message types.  Each location has a unique site AS2 ID... but I'm having some difficulty setting up the Party to handle all the sites.  I known Roles could handle this in Biztalk 2010... but is there a way to have multiple Parties using the same AS2 identifier ( the AS2-To value in the Party as AS2 Message Receiver ) in Biztalk 2009?  With the default content type settings, can a Party even be setup to handle both EDIFACT and X12 at the same time?  Biztalk 2009 won't let me setup multiple Parties using the same AS2-To identifier.
