Issue when mapping the connections on PBI Service - composite model

I have a PBI semantic model where I used live connection to an SSAS tabular model deployed on Azure.

I wanted to add an Excel file, so I had to add a local model and the connections were switched as described here Use composite models in Power BI Desktop - Power BI | Microsoft Learn

The connection changed to Direct Query on the PBI file.

The problem now is when I publish the datasource got disconnected :

 

 

What I have already configured?

A cloud connection created on the PBI service for SSAS tabular model but I noticed in the screenshot it is forcing me to switch to an On-prem connection while it still in the last section shows the cloud connection.

Why am I having this behavior ?

  • Hello AmiraBedh 

     

    When combining a cloud-based SSAS connection with a local Excel file in a Power BI composite model, a standard on-premises gateway is required for the Excel component due to Power BI’s architecture and security

     

    The behavior occurs because composite models with mixed data sources (cloud SSAS + local Excel) require a standard on-premises gateway for the Excel component, even

    By isolating the gateway requirement to the Excel file and validating SSAS’s cloud configuration, the conflicting UI behavior should resolve

    hope this is helpful

    It's much worse than that.  If you are combining these data sources then your cloud source must now also use the gateway.  MUST !!! And there is no going back! Unless you delete everything and start over.
