This is a pretty basic question but I'm struggling. Have tried searching but can't find the answer.
I have 10k. properties with a date against each e.g. when the kitchen was installed in. The column just contains the date.
For a 30 year business plan I need to identify which year the kitchens will need replacement based on a 20 year life cycle. I have columns 2017/18, 2018/19 etc. for the 30 years. If the kitchen was installed in say 1997 it will require replacement in 2017/18.
Starting with 2017/18 I'm trying to identify all properties which had the kitchen replaced between 01/04/2017 and 31/03/2018 and will then change the formula for each subsequent year/column.
Thanks in advance. Chris
