Field mappings in Microsoft Project

TFS 2018 | TFS 2017 | TFS 2015 | TFS 2013

You can customize how data is mapped between Microsoft Project and Team Foundation Server (TFS) by modifying the Microsoft Project Field Mapping File. The mapping file associates the reference name of a work item tracking field with a Project field. Before you change the Microsoft Project field mappings, you should review the information provided later in this topic to understand how TFS copies data from Project to the work item tracking database.

Important

Support for Office Project integration with Azure DevOps is deprecated starting with Azure DevOps Server 2019. The TFSFieldMapping command is not supported for Azure DevOps Server 2019 nor for Azure DevOps Services. Starting with Visual Studio 2019, the Team Foundation plug-in for Office no longer supports Office Project.

Note

The supported set of Project field names may be different for different versions of Project.

Calculated fields

Generally, you do not want to refresh calculated fields from the work item database. For example, start and finish dates are typically calculated based on task duration and dependencies. If a team member were to change the start date of a task in Team Explorer, the change could introduce errors in Office Project when the field is refreshed.

Therefore you can configure calculated fields so that they are publish only, meaning that Project will publish changes for those fields to the work tracking data store, but not update them. For more information about how to configure fields as publish only, see TFSFieldMapping.

You can also prevent team members from changing calculated field values in Team Explorer by using the READONLY attribute in the work item form definition. For more information about the READONLY attribute, see Apply a field rule.

Note

The Agile and CMMI process templates already configure the start and finish dates as publish only mappings, and read-only in Team Explorer.

Mapping field types

When you publish tasks from Project to TFS, Team Foundation copies the data to the work item database. Also, when tasks are refreshed, the field data is copied from the work item database to your Project plan. For the field data to be copied correctly, the field types in TFS and Project must be compatible. The following table lists which Project field types are compatible with TFS field types:

Work item field type Project field type
DateTime Datetime.
Double Work, units, percentages, fractions, and any field type with a range of ±5.0 × 10-324 to ±1.7 × 10308.
History Not Supported.
Html Not Supported.
Integer Work, units, numbers, and any field type with a range of -2,147,483,648 to 2,147,483,647.
PlainText Not Supported.
String Text (maximum of 255 characters.)
TreePath Custom outline codes.

Important

Project does not populate the Resource Names field list with names of team members. Therefore, you must manually add names to the list. When you assign a work item to a resource in Project, you should specify the resource by its display name from Active Directory or the Address Book. If you assign a work item to a resource by alias or other shortened form of the name, you introduce an inconsistency that can cause validation errors.

For more information about work item field types, see Add or modify work item fields. For more information about Project field types, see the help about the pjField constant in the Project 2013 developer documentation.

Project field names

In Project you can map any field name that starts with pjtask to a field in TFS. For example, you can map pjTaskText10 to a TFS String field. These field names are used in the ProjectField attribute when you specify which TFS work item field maps to a Project field. For a complete list of the Project field names, see the help about the pjField constant in the Microsoft Office 2003 Software Development Kit.

Note

If you are using Project Server, there are additional fields that have "Enterprise" in the name, such as pjTaskEnterpriseCost1. TFS does not publish or refresh data to Project Server, unless you integrate it as described in Synchronize TFS with Project Server. Therefore, these field names are not supported with the Team Foundation add-in to Project.
