I'm using excel 2003 in a large procurement project.
I know the dates when the various equipment needs to be delivered to the
sight. I also know the various delivery-, shipping- and process times given
as a number of days or months.
The project involves 100's of items and I need to be able to revise either
date or delivery times etc. and this change should then be reflected in a
changed project start date.
So how do I subtract/add a known number of days/months from a date?
All help is sincerely appreciated!
