I am looking to do a custom layout to control the tray colour of an iView and folowing the documentation (http://help.sap.com/saphelp_nw04/helpdata/en/43/6dfbbbac847100e10000000a1553f7/frameset.htm) on creating a custom layout it mentions to go to the default_iView in the core objects and look at the com.sap.portal.iview.family attribute.
The issue is I can not find this attribute in either the standard iView dislpay editor of the PCD editor.
We are running Portal 6 6.40 SP15...
Does anyone know where to set this value??
