Refresh Power Pivot data imported into PBI Desktop

Hello,

I recently imported Power Pivot data from Excel into Power BI Desktop by using the Import -> Excel workbook contents function. After adding some columns to the Power Pivot, I tried to do data refresh in PBI Desktop. But I get an error message that says:

Microsoft SQL: Could not find stored procedure 'Wrap_P_[my company alias]_33788960

My Edit Permissions is already set to Windows. How do I resolve this issue and be able to refresh?

Thanks,

KC
