When you refresh a Form, an OLE DB error message is shown: "OLE DB error: OLE DB or ODBC error: Invalid column name; 42S22"
Apply the latest SQL Server Cumulative Update from Microsoft to your SQL and SSAS servers. This typically resolves the issue.
If the issue persists, refresh every single partition that uses a view as its source within this Model. It's also possible that the source view is missing a column, which would be called out in the error message.
