Update Only Specific Columns
 

When I need to do something in Excel, I use mostly macros so need some help
on this one as a macro won't do the trick. When a file is opened that has
links to several files, I want to only update specific columns (we are
finding that some people redo previous months which should not be done).

The first step, I know, is to turn off the auto linking but beyond that I
have no idea. Can someone point me in the right direction or have code from
which I can start?

Thanks so much, Jani
