I have created a MS Flow where when an email is received, it creates an entry in an excel file stored on OneDrive for Business. I am trying to create a dashboard which shows average time of receiving specific emails. It seems MS Flow doesn;t support the excel files which have calculated columns in them. And Power BI service doesn't support any kind of calculated columns, So I created the report using Power BI desktop and the .pbix file is stored on the OneDrive for Business. I am running into issues with refreshing the .pbix file on Power BI service where it says I need a Power BI Pro subscrition. I tried to install a Gateway on my maachine but it never shows up under "Manage Gateways" on the Power BI Service.
In short I am stuck in a weird no man's land where as flow doesn't support excel with simple formulae and Power BI service doesn't allow to create any calculated columns in the report I have to use .pbix as a middle man. If I expose my excel file directly to the Power BI service, it refreshed as advertised every hour but it is useless for me as I can't create report with the raw data. And I can't add additional fields in the file as Flow service doesn't like it. Any thoughts on this subject will be much appreciated.
