Yes I have followed the link.
On Machine #1, if I add NOFILTER to the existing source code, then the error message disappears.
On Machine #2, I don't need NOFILTER.
The source data is the same remote ODBC source for both.
Tools/Options for Data and Remote Data are the same for both.

I would be in a better position if I could make the need for NOFILTER on Machine #1 go away, but you have given me a workaround that helps a great deal. Thanks. Any further suggestions appreciated.
