Because in CRM 2011 the Form Assistant is gone I've created some 1:N Relationships between Activities e.g. a Relationship between Phone Call and Phone Call. What I've done is to create a Field Map to write the values of the parent phone calls Recipient field to the follow-up phone call. But no values are inserted to the new phone call.
The Field Map for Single Lookups or Text fields work as expected. Is this a bug or can anyone provide info how to implement the follow-up feature as it was there in CRM 4.0?
