Within the Project Object Model, the Application object has a method, FieldNameToFieldConstant(), that returns a PjField constant for use by the various SetField() and GetField() methods throughout the object model. More information on the SetField Method (and other associated methods) can be found here.

Unfortunately, when using the PSI, there’s no quick way to lookup the Guid for a field. This can be a problem, since the various CustomFieldsRow objects (Task, Resource, Assignment, and Project) do not include the name of the custom field, only the UID (for an example, look at the ProjectCustomFieldsRow entity in the Project 2007 SDK).

Retrieving custom field information in the PSI is accomplished by using the CustomFields web service. The code below is a class that implements a method to retrieve the Guid of a custom field using the field’s name and entity type. I had to chop the code up a lot because of space constraints, so I apologize for the excessive line breaks. This code assumes that you’ve set up a Web Reference to the CustomFields web service named WebSvcCustomFields.

Earlier today in the EPMFAQ Forums, there was a discussion concerning an issue in Project 2007 whereby the Duration on a Fixed Duration task is set to 0d if the Work on that task either rolled up or was set to 0h.

This is divergent behavior from Project 2003, and one that appears to be causing issues for a rapidly increasing number of users. Many of us within the community have been aware of this issue for quite some time, but there appear to be many people that are unfamiliar with this little conundrum, be they users, administrators, or consultants.

Here’s my response to the question:

The issue you are referring to manifests when the Work for the task is set to 0h, whether by rollup or entry. This results in the task’s Duration being set to 0d. This is true for all Task Types, including Fixed Duration.

Chris Fiessinger recently posted a list of links to the post-SP1 hotfixes here.

For your benefit, I’ve copied them here:

• Project Server 2007 – KB 941426
• Project 2007 – KB 941657
• SharePoint Server 2007 – KB 941274
