[gulevi]

Hello , 

Seems like my dashbaord has not refreshed since the 5th of May , I have done no changes what so ever in the dashabord . 

I cant find a place to fully understadn on what it fails to refresh 

I did get an eamil about it the other day.

An error occurred while processing the data in the dataset.
Refresh failed:

AI_OI_Operations has failed to refresh.
Failure details: The last refresh attempt failed because of an internal service error. This is usually a transient issue. If you try again later and still see this message, contact support.

The error is not indicative enough of the reason but could be an issue with your source data such as duplicate keys in a dimension table?

Well again I did not change anything so not sure what and where it falls , and on what , it access a few Kusto CLusters and get the data from it with a very simple query .
How cna I chance what is wrong here ?

Yes it is well understood that you didn't change anything with the report/dashboard. I am suggesting that the issue is with the data and not the report. For example, if you have a Customers dimension table and the Customers table has a unique CustomerID column, the data now might have a duplicate CustomerID now and your model is failing to refresh because it is expecting the CustomerID to be unique while the data source has a repeating CustomerID
