Error in Analyze in Excel - Connection String

[AndreaCBS]

Hello everyone,

I'm experiencing the following issue: In Power BI Service, when I click on the "Analyze in Excel" option and open the file, it throws an error stating that it cannot connect to the OLAP cube.

However, if I go to the data connection properties and modify the connection string name, it successfully connects.

How is it possible that when I download a report connected to the cube, which displays the data correctly, the "Analyze in Excel" option seems to insert an incorrect connection? And how can i fix it?

Hi @AndreaCBS 

Here's the explanation from the document:

According to my speculation, your problem here is the connection string in the Excel file might be incorrect and cannot match the correct OLAP cube so that you need to update the connection string.

You got it right — the issue is that the connection string in the Excel file is incorrect and does not match the correct OLAP cube, so it needs to be updated. Once you correct it, it works.

However, my issue is not with the Excel file itself. The client downloads the Excel file from the Power BI report on Power BI Service every 2-3 days, which means the problem will keep recurring. I’m looking for a way to resolve this issue once and for all.

Hi @AndreaCBS 

Consider updating the Connection String in Power BI, open the Power BI Desktop file that was used to publish the report to the Power BI Service. Go to the "Transform Data" or "Get Data" > "Data Source Settings" to find the data source for the OLAP cube. Update the connection string to the correct one that points to the OLAP cube. After updating, republish the Power BI report to the Power BI Service.

Or you can create a template Excel file with the correct connection string to the OLAP cube. When you need to update the data, export the latest figures from Power BI to CSV or Excel, and then import this data into your template Excel file.

Do you know if there's something that can be done from the tenant administration portal?

Hi @AndreaCBS 

As far as I know, this issue should not be related to the Tenant Administration Portal.

Maybe you can create a support ticket for free and a dedicated Microsoft engineer will come to solve the problem for you.

It would be great if you continue to share in this issue to help others with similar problems after you know the root cause or solution.

Thank you for your understanding.

I tried to update the connection string then republish the Power BI report to the Power BI Service. But if Analyze in Excel once more, I have the same issue.

I tried different approach, hopefully I will persuade the customer to do things in a different way. But now what's most important to me is how fix this issue.
