Can we update the dataset without deleting and adding again?
Typically, I work with Excel or Power BI Desktop programs and build my data model there. You can, under specific circumstances, add a column for instance and the next time you refresh, it will be added to your data model. This does not tend to work if you create calculated columns. You have to remove the calculated columns and then refresh and then add the columns back.
If you do it this way, update the data model and then load the PBIX or Excel file and overwrite the old data set, you will not break all of your reports, dashboards, etc.
Ok, I see how you get the message about replacing the file- it appears if you click "Get Data" in the bottom left as opposed to clicking the + sign next to Datasets. However, it did not ask me that question if I picked a file from One Drive, which is where my Excel file is. When I picked "local file" option, it did ask me that question and I've been getting an error though after clicking to replace the file. I tried replacing a different dataset and it worked without an error but not really- I didn't see my new columns. So still a little puzzled
I closed my browser tab and opened a new session and now I see my new columns! :)
I found a better work around for anyone that sees this. Instead of removing all calculated columns, add a new "fake" one. This schema is updated and all data shows up after a refresh.
