Today I came across the below error and how to fix it.
- Open “Central Admin Manage Service Applications Performance Point”
- Open “PerformancePoint Service Application Settings”
- Below “Secure Store and Unattended Service Account” specify a user name and password for PPS to use for opening data sources.
- Click OK. Close the Dashboard Designer application and come back in clean. It should work just fine now.

PerformancePoint Services has not been configured with a valid Unattended Service Account. The setting is located in "Manage service applications" in SharePoint Central Administration under the PerformancePoint Services management page.
