I posted this as a question but got no reply and so assume it is not possible but it would be really useful.....
we have fields on the contact record which are linked to the company
record. In contact view these fields can be edited. This is
1) As soon as someone changes the field data in company view it will
over write the linked field in the contact view. (what I want is for the
user to understand this happens and not be able change the data in contact view
but go to company view)
2) Because there is no restriction users forget or don't bother to create a company
If in ACT layout designer you could have the concept of a read only field view then this would work.
Note - If you go to the database field definition and make this read
only then you cannot change the data at all, even from company view !
