Microsoft Project Mapping File
TFS 2018 | TFS 2017 | TFS 2015 | TFS 2013
You can customize how data is published and refreshed by modifying the Microsoft Project mapping file. When publishing or refreshing tasks in Project, the mapping file determines how Project task fields map to Team Foundation Server (TFS) work item fields. Also, the mapping file controls the publishing behavior. You can control if fields are only published, or both published and refreshed.
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.
If you are using Project Professional to synchronize tasks with work item data, then you must Customize the field mapping between work items and Project Server.
