Hi @mark-alford 

Are you still having problems with your datamart refreshing at the moment?

Yes, still the same error.

Advocate I

this is breaking my dashboards big time! Microsoft please help!

Frequent Visitor

Yes me too from Paris and bonus all my work from that day has disappeared, it's as if the dataset was returned to this morning...

Frequent Visitor

London calling 🙂

I had to re-create our (thankfully only one) datamart into a pbix and i then published it as a shared dataset which the end user reports are now pointing to. We lose some features of the datamart but at least the users are happy. Hopefully the issue will be resolved so we can revert back to the datamart, at the moment datamarts are effectively broken.

Helper I

Does anybody got any workaround which is working?

Anyone knows if MS is on? and if there is a date?

Advocate I


Hello. I find it a bit concerning, that a concept like datamarts gets introduced and later dropped (is this related to the introduction of Fabric?)


If you need any more info to make this a ticket, please let me know!

Advocate I

Do all datamart report this error? Yes.


Or is there a problem with a specific datamart? no.


What is the relevant data source? MySQL


If you recreate a new datamart, does it report this error? Yes, I recreated it this morning - same thing.
