An issue that I recently came across was when we upgraded our servers from BizTalk 2006 to BizTalk 2006 R2 is that we were unable to see the new EDI features. This is the context menu I saw when right clicking the parties:

The resolution is that after you upgrade the server, you need to need to modify the installation in the add/remove programs and choose Modify:
Check the BizTalk EDI/AS2 Runtime:

Then you get all of the components you are looking for.
