Cant access SSAS with Power BI gateway

[Novus-0]

Hello,

I m new working with Power BI. I made a simple dashboard and report with Power BI Desktop. Both are connected to my local Analysis Server (SSAS) and both are working fine. Now I uploaded all (report, dashboard and dataset) to my Power BI App. I also installed a on-premise-gateway and configured a datasource, including adding my dataset to the corresponding datasource (both SSAS connections). Gateway and datasource got the status "online" in my gateway-management-window. 

But as soon as I want to see my report or dashboard, I got the error message "this report cant access to the datasource. please contact the author".

Whats kinda weird is, that I also made a another report but using a connection to my SQL Server instead and it works. 

In conclusion: 

- I can access SSAS and SQL Server with my Power BI Desktop

- I can access SQL Server with Power BI App and my Gateway

- I cant access SSAS with Power BI App and my Gateway

What am I missing here?

your local cube is not a good POC platform.  Test with the real remote cube.

Then you likely need to use a personal gateway.

Why are you still bothering with SSAS?  is this a legacy cube?

Well, I want to check if I manage to connect Power BI with my local cube. 

When this works, I will try to connect it with a remote cube.

Hi @Novus-0 

Do you map your Power BI account to your local Active Directory UPN that has access to the AS server? When connecting to a SSAS database, you have to ensure the UPN mapping is correct after you add the data source to the on-premises data gateway in Power BI Service. Please refer to Manual user remapping in Power BI. 

You can use the following command from your workstation to find out the local Active Directory UPN for your account:

whoami /upn

Each time a user interacts with Analysis Services, the effective user name is passed to the gateway and then to the on-premises Analysis Services server. The UPN, which is typically the email address you use to sign in to the cloud Power BI Service, is passed to Analysis Services as the effective user in the EffectiveUserName connection property.

This email address should match a defined UPN within the local Active Directory domain. The UPN is a property of an AD account. A Windows account must be present in an Analysis Services role to have access to the server. If no match is found in Active Directory, the sign-in won't be successful.

Hi!

My UPN email adress is the same as the one I use for Power BI. 

And my windows account is present as a admin-role on my SSAS. I forgot to mention, that the SSAS I m trying to connect with is on my local machine (for testing purpose).
