Issue "Premium_ASWL_Error" when there is a merge between SQL & Sharepoint tables.

[giovannymb]

I have two tables with different data sources: one is fed from SQL and the other from SharePoint. Additionally, I have a step with a merge that works well.

When I update the report on my local Power BI Desktop, there are no errors or alerts. However, when I publish it on Power BI Service and the report is updated, the following error appears:

"{"error":{"code":"Premium_ASWL_Error","pbi.error":{"code":"Premium_ASWL_Error","parameters":{},"details":[{"code":"Premium_ASWL_Error_Details_Label","detail":{"type":1,"value":"Cloud data source setting is not allowed refresh through gateway."}}],"exceptionCulprit":1}}} Table: MyTable."

If I delete the merge step on PowerQuery, the report updates without any problem, but if I include the merge step, the error described above appears.

I don’t have any tables with Direct Query, calculated columns, or calculated tables. The connection to the gateway is working properly, and all the source credentials are well set.

I appreciate a lot if you can help me to solve this issue!

Hi @giovannymb,
Thanks for reaching out to the Microsoft fabric community forum.

It looks like you are facing a Premium_ASWL_Error when trying to refresh your report in PowerBi Service. This issue occurs when there is a mix of data sources or how PowerBi Service handles data refreshes for cloud and on-premises data sources.
Looking at the error it says "Cloud data source setting is not allowed refresh through gateway" which means that PowerBi Service is trying to refresh a cloud based data source (i.e. SharePoint) through an on-premise data gateway, which is not supported. Also as we are merging both the tables, PowerBi Service may process both the tables using the same data source settings, even though one table is from on-premise and other from Cloud Service.

Here are few points you need to check in order to solve your issue:
* Check your Data Source Configurations and confirm that your SQL Server data source is configured under the gateway while your SharePoint data source is configured as a cloud data source without using the gateway.
* You can also isolate the merge operation to avoid combining both cloud and on-premise data sources in a single query. And load the data as two different tables and combine them later in PowerBi model using relationships as suggested by @ToddChitt.
* If you still wants to perform the merge step in Power Query then make sure that the SharePoint Online source is configured as a cloud data source in the PowerBi Service.

Apply all the changes and republish the report. You can manually trigger a refresh and check the refresh status to confirm if the issue is resolved.

If I misunderstand your needs or you still have problems on it, please feel free to let us know.

What is the ultimate purpose of the MERGE operation in Power Query, and can you live with two tables that have a relationship defined between them. Obviously, you probably want to do some logic that involves columns from both tables, but you can get that with the RELATED DAX funtion.
