[Data Refresh Error] - LargeModelMovedAcrossRegions

Hi AnthonyLEVEILLE,

Thank you for reaching out to the Microsoft Fabric Community Forum. Also, thanks to lbendlin, for his inputs on this thread. I understand how disruptive it is when several dataset refreshes suddenly fail without any changes from your side.

From the error details:

LargeModelMovedAcrossRegions
URI: WABI-SOUTH-CENTRAL-US-C-PRIMARY-redirect.analysis.windows.net

it appears that the affected datasets are large semantic models that are now being accessed through a different Azure region than the one where they were originally created.

Your models expect to be hosted in France Central, but the service is attempting to refresh them through South Central US. Because large models are “region-locked,” moving them (or the workspace/capacity) across regions is not currently supported, and that triggers this error.

Hope this clears it up. Let us know if you have any doubts regarding this. We will be happy to help.
