Direct link to Windchill object

Hi,
we'd like to have direct links from our ERP system to Windchill EPM Doc pages.

I can export BranchId and construct link for an exact EPM Doc iteration.

http://www.example.com/Windchill/servlet/TypeBasedIncludeServlet?oid=OR%3Awt.epm.EPMDocument%3ABranchID&u8=1

But in case that Windchill object will iterate and ERP link not — is it possible to construct similar simple GET link which will always point to the latest iteration?

I have tried to send EPM Doc Master's ID but it didn't work.
