Invoked Custom Function not working on shared data model

v-lili6-msft ,

Thank you for your response, I went to the link you provided and that is exactly the same way I am creating this function.

I dug a little more into this as I was trying to come up with a sample data model and what I've found is that the custom function works great among shared data models until I connect it to the on-premise gateway. What could potentially be the cause of that? I see that all of my data sources are successfully connecting, and the credentials on those sources are fine, but the data still isn't appearing?

I don't think a sample pbix file will help in this case because you wouldn't be able to connect to our organization's on-premise gateway. Could this be due to a recent update?

Thanks again.
