Cannot update ADODB.Recordset because it is read-only. (Error 2083)

Occurs when the supplied ADO Recordset is in a non-updatable configuration and is set as the data source.

Make sure the ADO Recordset is configured to support updates. The ADO Recordset must typically have its CursorType property be adOpenKeyset, adOpenDynamic, or adOpenStatic, and its CursorLocation property must typically be adUseClient.
