I was recently working on a AS2/EDI project using BizTalk 2006 R2 and came across
an interesting question:

How do I create 500+ parties? and with the AS2 Properties included (or even
HL7 for that matter)

After a little digging – there is the BizTalk.ExplorerOM that we could drill into
and create the parties through code.

However, there’s a more hands off approach….using Bindings!!!!

(1) Export Bindings from an existing setup including Parties!!! to
an xml file.

(2) Modify the XML file – particularly the Party information.

(3) Import Bindings back into your new environment.

There’s a great blog post by the BizTalk Team on this subject a while back – http://blogs.msdn.com/biztalkb2b/archive/2006/10/25/automated-deployment-of-edi-properties-also-useful-for-bulk-import-of-party-properties.aspx
