Managing Field Mappings for Integration of Team Foundation Server and Project Server

Updated: June 2011

You can customize how you synchronize data between Visual Studio Team Foundation Server 2010 and Project Server by modifying the field mapping file. This file defines the data fields that are synchronized and how they are synchronized to support the integration of Team Foundation Server and Project Server. You can manage this file by using the following options of the TfsAdmin ProjectServer command-line tool:

  • /DownloadFieldMappings: Downloads the field mapping file that is defined for a team project collection.

  • /UploadFieldMappings: Validates the XML syntax of the field mapping file, and uploads it to a collection. To validate the syntax but not upload the file, you can use the /validateonly option.


The field mapping file for the integration of Team Foundation Server and Project Server is distinct from the field mapping file for Microsoft Project. For information about how to download or upload the second file, see TFSFieldMapping.

For more information about the contents of the field mapping file and how to customize it, see Field Mapping XML Element Reference for Integration of Team Foundation Server and Project Server and Customizing the Field Mapping Between Project Server and Team Foundation Server.

To use the TfsAdmin ProjectServer command-line tool, open a Command Prompt window on a computer that is running Team Explorer and Visual Studio Team Foundation Server 2010 Service Pack 1. You run the tool from the following directory: Drive:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE. For 64-bit machines, the tool is in Drive:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE.

Required Permissions

To use these commands, your Administer Project Server integration permission must be set to Allow for the team project collection. Also, the service account for Team Foundation Server must be granted the necessary permissions to interact with the instance of Project Web Access or Project Web App (PWA) that will participate in data synchronization. For more information, see Assigning Permissions to Support Integration of Project Server and Team Foundation Server.


Even if you log on with administrative permissions, you must open an elevated Command Prompt window to perform this function on a server that is running Windows Server 2008. To open an elevated Command Prompt window, click Start, right-click Command Prompt, and then click Run as Administrator. For more information, see the following page on the Microsoft website: User Access Control.


TfsAdmin ProjectServer /DownloadFieldMappings /collection:tpcUrl /filepath:mappingFile [/encoding:encoding]
TfsAdmin ProjectServer /UploadFieldMappings /collection:tpcUrl /filePath:mappingFile [/encoding:encoding] [/validateOnly] [/useDefaultFieldMappings] [/force]




Specifies the uniform resource locator (URL) of a team project collection. You specify the URL in the following format:


If you do not specify a virtual directory, you specify the URI in the following format:



Specifies the path and file name of the XML definition file that contains the field mappings.

If you are using Windows Vista, you might not have permissions to access certain folders. If you try to export the work item type to a location where you do not have permissions, the registry virtualization technology automatically redirects the exported file and saves it to the virtual store. To avoid this redirection, you can export the file to a location where you have permissions. For more information, see the following pages on the Microsoft website: Registry Virtualization and Common file and registry virtualization issues in Windows Vista.


Specifies the name of an encoding format for the .NET Framework 2.0. The command exports or imports the XML data in the encoding format that you specify. For example, /e:utf-7 specifies Unicode (UTF-7) encoding. If you do not specify this parameter, the command tries to detect the encoding and uses UTF-8 if detection fails.


Validates the mapping file but does not upload it.


Uploads the default field mappings instead of a custom mapping file. For more information, see Field Mapping XML Element Reference for Integration of Team Foundation Server and Project Server.


Overwrites the existing mapping file. You must specify this option if you specify the /useDefaultFieldMappings switch when you replace the existing mappings with different mappings.

You can map only enterprise custom fields or fields that are built in to Project Server. You must specify the name of a valid field in Project. To determine the name of a built-in field, remove any spaces from the friendly name, and prefix the result with "pj". For example, the field name for Status Manager is pjStatusManager, and the field name for Custom 01 is pjCustom01. Restrictions exist on how you can map built-in and custom fields, and you must match the data types of fields. For more information, see Restrictions on Mapping Project Server Fields for Integration with Team Foundation Server.

When you run a TFSAdmin ProjectServer command, a message indicates the action that is being performed and the affected object. For example, the following message shows that the field mapping file is being downloaded:

Download field mappings from Collection0

Another message appears after the command actions are completed. For example, the following message appears when the field mapping file has been downloaded:

You have downloaded field mappings to C:MappingFile. . . Done.

Notes about Uploading Field Mappings

If a field mapping file is uploaded successfully, the following changes are made:

  • Each mirror field in Team Foundation is configured to comply with the mapped fields.

  • For work item types that have been mapped for a collection or a team project, the new mappings appear on the Project Server tab of the work item form.

Important noteImportant

When you map a field from Team Foundation Server to Project Server, make sure that you match the data types of those fields. Otherwise, the following error might appear when you try to upload the field mappings:

Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

For more information, see Data Types and Field Mapping Criteria.

Download the Field Mapping File That is Defined for a Team Project Collection

The following example downloads the field mappings that are defined for AdventureWorksCollection to AWMappingFile.xml.

TfsAdmin ProjectServer /DownloadFieldMappings /collection:http://AdventureWorksServer:8080/Collection0/AdventureWorksCollection /filePath:"C:AWMappingFile.xml"

Upload the Field Mapping File for a Team Project Collection

The following example uploads AWMappingFile.xml to AdventureWorksCollection.

TfsAdmin ProjectServer /UploadFieldMappings /collection:http://AdventureWorksServer:8080/Collection0/AdventureWorksCollection /filePath:"C:AWMappingFile.xml"
