tfs - How to populate data for SharePoint Team Foundation Server web part burndown, bug progress chart -

we configuring team foundation server web part show dashboards associated burndown, user stories, etc. added active when click on bug progress link, chart not display data. click on burndown link add issues data. when click on task burndown or user story progress, following message

"the error occured during attempt establish connection external data source. following connections failed refresh:

tfsolareport"

i see data correctly populated in chart. appreciated.

you need administrator fix this.

they need validate configuration , rebuild data warehouse , cube.

this occurs because dba thinks know how configure sql, rs, or better microsoft. don't, , should not have permission of tfs subsystems. tfs owns , manages subsystems itself. don't change outside of tfs admin console without direct direction product team.
