CAFE1 - Edit, Add action from Child form

Hi,

I have the following question:

Is there a possibility to perform actions like add, edit from the child form of a CAFE1?

Case: I have made a CAFE1 where the parent is the P42101 (Manage Existing Order) and the child is the P4104 (Work with Item Cross Reference). When I select a record from the parent, the child is being populated with the item details, but when I am trying to edit or add, the system does not allow me to do that.

Thank you.

Antonis
