The biggest issue I have with the SaveAs method in Excel, and there is no
way to turn it off is when overwriting an Excel file with the same file
name, the confirmation message box of verifying that you want to replace the
file in the locaion with the file currently open, which then stops the code
at that point. Even if you set the "DisplayAlerts" property to "False"
boolean value (or 0), it still happens with that particular situation. This
is why I do not use the "SaveAs" method on any workbook.

How to get around this issue?

Instead of using the "SaveAs" method, use the "SaveCopyAs" method as it does
the trick and avoids the confirmation message entirely.

There is one other distinction between the "SaveAs" method versus the
"SaveCopyAs" method. With the "SaveAs" method, any formulas of any open
workbook dependent on the workbook being saved via the "SaveAs" method, they
will adjust to the new location. Using the "SaveCopyAs" method, none of the
formulas will be adjusted, even if they are dependent on the workbook being
saved via the "SaveCopyAs" method. The main reason why this is the case,
the "SaveCopyAs" method is originally meant to be used as a backup method,
so if something happens to the primary file, you have a backup way of
retrieving the file without hurting anything. To retrieve the file from the
backup location, just use windows explorer to copy it from it's backup
location and paste it to the original location.
