Exporting Work Items to Office Project

For information about connecting, disconnecting, and working offline in Excel and Project, see the following topics:

When you import work items into Excel or Project, local copies of your work items are created. The data in the local document at first matches the data in the database, but you or other team members can change the data about work items and cause the two to differ. To view the most recent changes from the database, refresh the document. This downloads the latest values in the data store to your local document. To write changes from the document to the database, publish the changes. Publishing uploads the changes you made to the work item tracking data store.

Resolve publishing errors

Review the following topics to resolve any publishing errors that arise when working in Excel or Project.



Resolve data conflicts. A data conflict occurs when one team member changes a field value in either Microsoft Project or Microsoft Excel at the same time another team member changes the same field in Team Foundation Server. You can use Team Foundation Server tools to resolve these data conflicts.

Resolve Data Conflicts

Resolve invalid links in a tree. An invalid link occurs if a team member views work items in Microsoft Excel as a hierarchy or tree list, and moves a work item or sorts the list so that it breaks the dependencies between work items. You can resolve this error by reviewing the error message and repositioning work items to reflect the work item structure.
