Any ideas why I would get a "Data Not Available" error when editing a custom field?
In this specific instance I'm editing a formula field, and I'm able to edit and save changes to the description and help text, but when I edit the formula I get a "Data Not Available" error.
I'd thought this might be a browser issue and cleared everything and retried, same result. What could cause this sort of thing?
In this specific case, I was changing the formula from
Field1__c - Field2__c
MAX(0, Field1__c - Field2__c)
