HI all, thanks for your answer
I think I've found a way around it, bit this creates a new question
I've added the Code columns in my resource sheet, so there aI can add Inactive if the resource doesn't work for us any more, that lets me filter based on code different to inactive.
Custom filters don't seem to work when you open the project (e.g. I save when I have the view I need (Resource Sheet, filtered by my custom filter Active resources), but when I restart MS Project, the All Resources filter appears instead. The only way to go back to the view I need is to select some other view and then go to the Resource Sheet view
ANY TIPS ON HOW TO TELL MS PROJECT TO REFRESH THE FILTERS WHEN STARTING?
Thanks!
