I am trying to create child cases for a case using workflows. This workflow would trigger on an incoming email to CRM. I need to set the customerid as the person who sends the email and not the customerid of the parent case. The two can be different. While setting it as Sender (Email)/Sender(Contact) it doesn't work and gives the following error:
Creating Entity with an invalid parent. Entity: Incident, ReferencingAttribute:customerid
Can the experts out there please help me with this one?
Note:- For the case entity, activities is already marked/ticked under Communication & Collaboration.
