Can's save dataflow - Linked tables can't be modified

[Anonymous]

Hi everyone, 

On multiple occasion dataflows cannot be saved because of the below error:

"Linked tables can't be modified. Please undo any changes made to the following linked tables and try again"

We have Power BI Premium and it worked just fine before. Since a couple of weeks we're getting these errors and this means we cannot save our dataflows. Of course we know about the workaround to disable a query for load and then reference it, but we have multiple queries in 1 dataflow and multiple dataflows, so this would mean A LOT of unnecessary extra work. 
Seems like a bug to me, but cannot find any other users/members having issues with this.

Who can help / knows the solution?

Thanks in advance!

Best Regards,

Hi, @Anonymous ;

Please check the Limitations and Considerations of linked entities to see if this is the cause.

There is a similar case reported in Issue forum you may refer to : Unable to save a dataflow . Or you may update the on premise data gateway to the latest version to avoid potential issue.
