Lakehouse Table Mapping Unidentified
I have a lakehouse that mirrors my production lakehouse. I have had no issue with the tables in the past but just this last week I received an error on my mirrored lakehouse: "Unable to identify these objects as tables or views. To keep these objects in the lakehouse, move them to Files" I have tried to move the tables to files and reconvert them to tables but it does not allow me to convert to file. I get the error: "Unable to move all unidentied items to Files". I am unsure on what to do to get these tables to start working again. Any suggestions? My next step if I am unable to figure this out is to recreate the lakehouse and remirror the data. I would prefer to avoid this as I have multiple reports that feed off this lakehouse so would like to resolve this if at all possible.
Hello JDay98
The issue with schema shortcuts is typically caused by:
- A corrupted or partially synchronised schema metadata file
- Modifications to the underlying Delta transaction log at the source
- Desynchronisation of shortcuts following schema evolution
- Inconsistent metadata within the mirrored lakehouse
Before addressing your mirrored lakehouse, please ensure the source is in good health.
Within your production lakehouse, confirm that /Tables exists and contains the *_delta_log:
Fabric shortcuts may have become outdated.
To refresh:
- Select the relevant schema shortcut
- Click Refresh
If the refresh is unsuccessful, it is likely due to metadata corruption in either the shortcut or the source.
From the mirrored lakehouse:
- Go to SQL Endpoint → Refresh
- Navigate to Tables view → Refresh
- If the problematic table displays a warning, select “Remove from SQL endpoint”
This action removes only the metadata and does not affect the actual data.
