PowerPivot in PowerBI Report Sever - Which SQL version meets?

[Anonymous]

Hi Masters,

We planned to migrate our excel reports to PBIRS, configured SSAS and SSAS in PowerPivot model with SQL2012 +SP4.

Most excels connectted to SSAS works, but excel with PowerPivot not. We got error message as below:

We cannot locate a server to load the workbook Data Model.

We have checked ULS log, the OOS communidate to SSAS powerpivot model seems OK: 

Checking Server Configuration (SERVERNAME\POWERPIVOT) ...
--> Check Administrator Access (SERVERNAME\POWERPIVOT): Pass.
--> Check Server Version (SERVERNAME\POWERPIVOT): Pass (11.0.7001.0 >= 11.0.2800.0).
--> Check Deployment Mode (SERVERNAME\POWERPIVOT): Pass.
Check Server Configuration (SERVERNAME\POWERPIVOT): Pass.

Can PBIRS + PowerPivot work under SQL2012+SP4? or need higher SQL version?
