I'm trying to create a custom formula field on Activities to subtract the Activity date (task or event date) from a custom Account field date (Account Transitioned Date). I am using a Report Type of Accounts w/or w/o Activities so that I can find Accounts where there isn't an Activity logged at all or an Activity is logged but it isn't within 30 days of the date in the Account field: Account Transitioned Date field. Is this possible?
