Status 7 Calling ProjectCreate From PDS

[dil]

When I send the following request to PDS.

<Request>
<ProjectCreate>
<Project>
<ProjectName>CreatedProject.Published</ProjectName>
<StartDate>20020923</StartDate>
<Milestones>
<Milestone>
<TaskName>Project Milestone</TaskName>
<StartDate>20021031</StartDate>
</Milestone>
</Milestones>
</Project>
</ProjectCreate>
</Request>

I'm getting following error

<Reply>
<HRESULT>0</HRESULT>
<STATUS>7</STATUS>
<UserName>Administrator</UserName>
</Reply>

I'm using Administrator Account to send above request.
According to the documentation Status 7 is rsNodeNameInvalid , The node
name
is not recognized as valid syntax for the request.

I don't think the XML has any problem. Because I copied a sample from
MS Project SDK to send, I got same error. I can connect from Project
Pro to server, and can publish project to server.
I don't know that's wrong on it. I checked Create Project Permission,
it was ok.

I'm using Project Server 2003 SP2a, and using PDS in VS C#.NET.

any idia?

thanks,

Dil
