TFS comes with few standard sample reports. For these reports they have Cubes (SSAS) as back end and SSRS as front end. Cubes datasource is datamart. And there is a SSIS package which imports data from SQL server to Datamart.
Now we have created a custom field in TFS which is saved in SQL server. but this fields is not in datamart or in cubes. I need to create a report using this custom field.
