ServerError_DMTS_MonikerDatasourcesNotFoundErrorCode on dataset refreshes

[LukeB]

We've had dataset refreshes set up and have done for a long time (3-4 years). This morning a random selection of our datasets got the error message ServerError_DMTS_MonikerDatasourcesNotFoundErrorCode (screenshot 1). When checking the datasets (screenshot 2) it appears that the data source connection has randomly dropped off for the datasets. Why has this happened?

To fix this I had to go into each dataset and reselect the data source connection from the dropdown list under the "Maps To" part (Screenshot 2) and manually refresh the dataset

@KarenL7 No I didn't raise a support ticket as the resolution for us was to re-map each dataset to the pre made data source connection. It's just strange how that mapping had randomly dropped off.

I assume Microsoft made a change or an update that may of affected this as I can see other people have raised this today with the same issues.

@LukeB - I did not see your message yesterday.  I did note that late yesterday this issue was suddenly resolved. 

Microsoft did not ask for any of us to create a support ticket?  I am unsure if you did? - but can confirm all is good now - I am unsure what Microsoft put in place to fix - hopefully all is good for you now.

Thanks

Karen
