PowerBI with Snowflake released refresh error: 'Implementation' are not valid Snowflake options.

Hi SteveShen ,

This is a classic version mismatch between your Power BI Desktop and your On-Premises Data Gateway.

Here is exactly what is happening:

• Your Desktop: You are on the November 2025 release (v2.149). This version introduced a newer Snowflake connector (Implementation 2.0) likely for better performance using Apache Arrow.

• Your Gateway: The Gateway installed on the server is likely an older version that does not yet recognize the Implementation="2.0" parameter. That is why it lists the "Valid options" and Implementation is missing from that list.

How to fix it:

Option 1: Update the Gateway (Recommended) Ask your IT or Admin team to update the On-Premises Data Gateway to the November 2025 (or latest) version. Once the Gateway matches your Desktop version, it will understand what "Implementation 2.0" means.

Option 2: The Quick Workaround (Edit M Code) If you cannot update the Gateway immediately, you can force the report to use the legacy connector:

1. Open Power Query Editor.

2. Select your Snowflake query and open the Advanced Editor.

3. Locate the part Snowflake.Databases("...", "...", [Implementation="2.0"]).

4. Simply remove the [Implementation="2.0"] part so it looks like Snowflake.Databases("...", "...") or just Snowflake.Databases("...", "...", []).

5. Publish the report again.

The Gateway should accept the request since it defaults to the old implementation.

Hope this gets your refresh working again!
