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 both 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. If so, fix this to View in the Type column.
