Hi,
It can be done as a combination of JavaScript+Java in Alfresco.I created a processdefinition.xml which invokes my Custom ActionHandler.
java script code executing as a rule :
processdefinition.xml
ActionHandler
Along with this, I updated permissions for "Under Review" so that admin is coordinator for it & Approver is consumer for it.
