Hi there.
I would very much appreciate some guidance on this issue -
I am trying to create a DataFlow in PowerBI service, with incremental refresh from SQL Server database of a table which updates with a new set of data everyweek. Data table loads fine into PQ online when I connect it for the first time but when I try to run it after enabling the Incremental refresh, the update fails. Any idea what am I missing?
Here are the info and checks done - Weekly data 100k rows, Premium per user Trial mode, Gateway connection configured and running fine and Privacy level set to Organisational and below is the error message. Please note that the incremental refresh is based on a 'ReportDate' column which carries the Reporting week Date stamp for all rows in table and changes every week.
There was a problem refreshing your dataflow. {"RootActivityId":"14467eb1-2df9-1212-95d8-8c2df798650d", ErrorMessage:"Encountered user gateway exception: '[DM_ErrorDetailNameCode_UnderlyingErrorCode]=-2147467259 [DM_ErrorDetailNameCode_UnderlyingHResult]=-2147467259 [Microsoft.Data.Mashup.ValueError.Class]=20 [Microsoft.Data.Mashup.ValueError.DataSourceKind]=SQL [Microsoft.Data.Mashup.ValueError.ErrorCode]=-2146232060 [[Microsoft.Data.Mashup.ValueError.Number]=-1 [Microsoft.Data.Mashup.ValueError.Reason]=DataSource.Error [InnerType]=MashupValueException Microsoft SQL: A network-related or instance-specific error occurred while establishing a connection to SQL Server.

Hi @agarwal137 ,
If you have configure the gateway well? Did the manually refresh work well? It seems to be connection with sql server. First, please check the following link: https://sqlbak.com/blog/sql-network-interfaces-error-26-error-locating-serverinstance-specified
If this post helps, then please consider Accept it as the solution to help the other members find it more quickly.

So your SQL server network connection is wobbly? Maybe you want to fix that first.
Initially, I thought that too but the query runs in like 5 mins on MS SQL studio whereas in Datafow, it goes on like forever. Internet conenction is also fine.
"after enabling the Incremental refresh, the update fails. Any idea what am I missing?"
You forgot to include the failure details. You could be running into a query timeout, you could run out of space, or it could be something else. Please provide more details.
@lbendlin Thanks you taking a look at the query. I have updated the details. Please let me know if anything else is needed.
