Hi Ken,
I don't know much about cube formulas, as I am not using them myself. But I know following refresh options:
- Go to Data tab, choose "Connections", your connection and the click on the "Refresh" button
- Go to Data tab and choose "Refresh All". If you have multiple connections that might not be best options
- Go to Data tab, choose "Connections", select your connection and click "Properties". There you will have an option to set:
"Refresh every x minutes"
and/or
"Refresh data when opeing the file"
So as you stated, you need to refresh pivot data connection first, I don't know any other way. But I listed refresh options above in case it might be enough for you to refresh for example very 5 minutes.
