Unable to refresh an Excel Workbook linked to a dataflow

More Details.

1) I set up a data flow in a powerbi workspace with sets of data

2) I created an excel workbook that is saved in my Personal One Drive because whenever i try and upload from the cloud one drive, i get the following- 

"This file is located on your OneDrive for Business or on a SHarePoint Online team site and can only be published to your own Power BI Workspace"

3) Uploaded the worksheet to a PowerBI Workspace

4) Go to workbook settings to schedule refresh and get the following:

You can't schedule refresh for this dataset because the following data sources currently don't support refresh:Learn more about data sources that currently support refresh.

Is it possible to have a scheduled refresh linked to a data flow that lives in a workspace?
