Failed to refresh dataflow after changing underlying data

I created a dataflow targeting a table in my Azure SQL DB.

 

I did some changes and removed and added columns to the underlying table.

I hit Edit on my entity in the dataflow, verified that the data preview was in accordance to the underlying table and hit Save and Close.

 

If i now expand my entity so that i can see the Columns and Datatypes the changes are not reflected. I tried to update my Dataflow and is met by a failure with reason that it cannot find the columns that I removed from the underlying table.

 

If I deleted the query against this entity in the dataflow and added a new one targeting the same SQL table the problem persist.

 

The only fix for this is for me to create a new dataflow targeting the updated SQL table for the changes to come through.

Hi @lbendlin ,

 

You are getting error : The"xxx"column does not exist in rowset, is it right?  It is by design, modifiying the structure of a data source will cause this problem. You need to republish it.

Ok, so its not a bug but a feature?

One would imagine that using edit on a dataflow entity to update and refresh the data would also save the eventual changes.

Imagine deploying a self-service BI structure to an enterprise wide Power BI organization and having to update each and every dataset and app with the new source parameters. 

If what you are saying is true then one would have to make sure that the underlying table in the source never changes or youll be in a heap of administration problem updating all the dependencies.

I thank you for your reply and will mark it as the solution. Even though i wouldve hoped to have this acknowledged as a bug.
