![image-20240625-042111.png](media://d8949ae2-d507-41e4-8a46-997a95975cdf)


**Cause**: Tables that have been registered in DataShed4 have been renamed or removed in the database. DataShed4 is still trying to reference those tables

**Resolution**: Check in the `tblSYSDSConfig` for the tables causing the error. Once located remove the entries from the table.

example using the following table example `tblLIBProdParentStope` `tblLIBPRODMovementType` `tblLIBProdBlockSource` Update the query to the tables in the error.

Select statement:

```sql
select * from tblSYSDSConfig
where BaseName in ('tblLIBProdParentStope', 'tblLIBPRODMovementType', 'tblLIBProdBlockSource')
```

Delete Statement:

```sql
Delete from tblSYSDSConfig
where BaseName in ('tblLIBProdParentStope', 'tblLIBPRODMovementType', 'tblLIBProdBlockSource')
```

> ⚠️ Before any change is made to a user database (or system), maxgeo recommends competent staff should follow all standard database change management practices and never make untested changes to a production database.  
> ⚠️ Change, test and document all modifications on a test copy of your database to ensure results are as expected before implementing them on your live database. Always ensure a full backup is available in case rollback is required and follow all company change management procedures and practices.
