Specifying Field Names According to Parent Id

The Parent Id Field applet user property specifies the name of a field that resides in the current business component. For example, the PS Project Team OrgChart Applet specifies the Parent Team Member Id field that resides in the PS Project Team business component. If the user drags and drops one box over another box in an organization chart to create a parent and child relationship, then Siebel CRM populates this field with the parent row ID.

If you do not specify a field, then Siebel CRM uses the default value from the Manager Id field that resides in the Contact business component.

You can configure Siebel CRM to deactivate this user property, but not to modify the value for it or to create a new instance of it.
