after migrate from TFS 2013 to TFS 2015 update 3 we got this error when trying to manually recreate cube for reports.
[Work Item Tracking Warehouse Sync]: ---> Microsoft.TeamFoundation.Warehouse.WarehouseException:
TF221122: An error occurred running job Work Item Tracking Warehouse Sync for team project collection
or Team Foundation server tfs_collection. ---> Microsoft.TeamFoundation.WorkItemTracking.Server.Metadata.
WorkItemTrackingTreeNodeNotFoundException: TF51541: The Node ID is not recognized: 1310 at Microsoft.
This error occurs for work item tracking warehouse sync. We had rebuild cube, still the same issue. Did you ever meet with this TFS issue? Thanks
