This is a good use case for a parameter. You could package both filters inside of a parameter, so only one or the other can be chosen. If you need help setting it up, please post a packaged workbook (.twbx) file that demonstrates your setup.
I have attached the Superstone sample dashboard as I am not supposed to share the actual dashboard.
We have 2 fields in it 1. Order Date 2.Ship Date.
Could you please apply the logic on these 2 fields ?
Thanks in Advance,

I won't have time to set this up for you anytime soon today. Perhaps someone else will step in to help you.
