Connect two NAV databases by consuming NAV WS

Lec11

Hello!

I'm trying to connect two NAV 2009 databases by using NAV web services. I was able to read data from another database by reading Freddy Kristiansen's blog: http://blogs.msdn.com/b/freddyk/archive/2010/01/22/connecting-to-nav-web-services-from-microsoft-dynamics-nav-2009-sp1.aspx. However I'm having difficulties in using page update method ... it seems much easier in using it in the .NET environment. Can somebody at least show me the right direction in using this method from NAV?

Thanks!

Meanwhile I became more interested in using .NET interop for consuming NAV web services from inside NAV. This happened after I found Waldo's very useful article http://dynamicsuser.net/blogs/waldo/archive/2010/12/30/nav-2009-r2-net-interop-calling-a-web-service.aspx.

I'm setting the security mode to TransportCredentialOnly, client authentication to windows and impersonation level to delegation. When I try to call from RTC the web service, I get the following authorization error:

---

This message is for C/AL programmers: The call to member Read failed: The remote server returned an error: (401) Unauthorized..

---

I get the error even if I run it from the same machine as the web service. Everything is setup correctly ... the web service is up and running, as long as I can call it with success from .NET application for example. Does anybody have an idea of what else do I have to check?

Thanks!

Problem solved ... changed client authentication to Ntlm and it works.

Access denied. Delegation or Impersonation permission is required for access.

the issue to the above error is delegation issue. You need to setup correct http SPN. take a look at MSDN documentation on how to setup 3 tiered environment.
