Microsoft Excel allows you to create a defined name to
represent a cell, range of cells, a formula or a constant value in the current
or in another workbook. For example, if a range in another workbook contains
sales figures, you can name the range CurrentSales, and then use the name
CurrentSales in your workbook, instead of referring to the range directly.
Note If you have a defined name in your workbook that refers to an external source, and that defined name is not used anywhere in the workbook, that link will not show up in the
Edit Links dialog box.

The link source for a defined name is not available in Excel 2002 and later
When you break an external link that is based on a defined name, all
formulas and references based on that link are replaced by their current
values. However, the link itself remains intact and you can continue to use it
in future references and formulas. To completely delete the link, you must
delete the defined name as outlined in the "Workaround" section.
