Re: Data source for dataset with incremental refre...

Valera · ‎08-02-2022

Hi!

There is a PBIX with data source options. I publish it to the workspace and try to update the data source via API endpoint.
But this endpoint does not update the existing data source but adds a new one.
As a result, the dataset has 2 data sources.
This behavior is observed only for datasets with an incremental refresh.
In regular reports, the data source is updated successfully.

How can I update the data source for such a report?

Thanks,
Valera

Hi Valera, did you get an answer for this? I have the exact same problem where it is creating a new datasource instead of updating on incremental refreshes.

Hi @Dan2
Unfortunately not. But we were able to bypass this issue via parameters. We added ServerName and DbName parameters to report:

And updated them using this endpoint: https://learn.microsoft.com/en-us/rest/api/power-bi/datasets/update-parameters

Hi @yingyinr,
Thanks for your answer.
Nothing from mentioned limitations is related to my dataset.
XMLA endpoints wern't used.
Data source is SQL server.
There are no parameters in connection details: just plain server address and DB name.
Also, there was mentioned that "The original data source and the new data source must have the exact same schema."
Not sure what it means, but seems to be not related to my case.
Here are API endpoints that I execute:
Retrieving of existing datasources:

Updating this datasource via UpdateDatasource endpoint:

Retrieving datasources after update:

As a result a new datasource was added instead of updating of existing one.
I also checked the same report without incremental refresh.
It works as expected. The existing datasource is updated.
