Hi Arjun,

This error is not VFP native error, it is coming from ADO. Apparently the Recordset is unable to propagate changes to the backend, it fails to locate the record. What OLEDB provider are you using? Is it possible that the record is modified by some means other than this CursorAdapter (triggers, other clients, other CursorAdapters)?

Thanks,
Aleksey.
