I am trying to create an activity report that encompasses all activity from Accounts, Contacts, and Opportunities. However, I do need to pull a custom field from the account record. When I go to create a custom report type and start with activities, it doesn't let me relate it to any other objects. When I start with accounts and relate opportunities, contacts, and activities, it seems that I may be missing portions of the logged activities. Any thoughts on how to commplish this?
