    Hi 101Mathew,

     

    Yes, currently this feature is only available in power bi desktop(preview) and is not supported for editing in the service yet.

    So any calculated columns/tables for Direct Lake need to be created in desktop and then published, there is no live edit option in the service now. Since it is still rolling out in preview, this behaviour can be expected.

    Please refer below documentation:

    Thanks and regards,

Hi Harrisontpowell,

 

Even after enabling the preview feature, this is still not fully available for all Direct Lake models or tables yet, that is why you are seeing this error. The rollout is currently phased and limited.

Please make sure:

  • You are on the latest Power BI Desktop (April 2026 or later)
  • The preview feature is enabled

If both are already in place and the issue still occurs, then it is likely due to the current preview limitations, as full support is still being rolled out.

 

Thanks and regards,

Hi v-achippa ,

I'm on the May-26 version now - I cannot see the preview feature for calculated columns/tables on Direct Lake model tables.

Should this be raise with MS support?

Regards,

Mathew

    Hi 101Mathew,

     

    Thank you for the update. This feature is still being deployed in phases, so it may not be available to all tenants or regions yet, it's likely still gradually rolling out. Please follow the below step:

    • Go to File --> Options and settings --> Options --> Preview features and look for an option related to Direct Lake calculated columns. If you do not see it listed there, then it means the feature has not rolled out to your environment yet.

    Then please raise a microsoft support ticket so that the team can confirm whether your tenant has received the rollout and investigate any tenant specific issues.
