Power BI Embedded does not support full XMLA read/write Power BI Embedded currently does NOT support XMLA Endpoint (read/write) like Power BI Premium.

Power BI Embedded (A SKUs like A1, A2...) only supports XMLA read-only (if enabled).

The function of deploying models via Visual Studio/Tabular Editor requires XMLA read/write, so you get the error.

You can check the XMLA support status in capacity settings here:

Log in to Power BI Admin Portal

Go to Capacity settings

Select the Embedded capacity you are using

Look for “XMLA endpoint”: you will see that it only supports read-only.

You can try

Using Power BI Premium (P SKU or F SKU)

If you want to deploy AAS/tabular models directly from Visual Studio or the Tabular Editor, you must use a workspace assigned to a Power BI Premium capacity (P or F SKU) — as only these SKUs fully support XMLA read/write.
