Hi Shiju John,

you can not get the sub process instance id from the parent process. This relationship between process instance and sub process instance is not stored in a table. 
But you can check the class +SubProcessNodeInstance+. This class represents a sub process call activity and start the sub process instance. See the following code:

ProcessInstance processInstance = ( ProcessInstance ) ((ProcessInstance) getProcessInstance()).getKnowledgeRuntime().startProcess(processId, parameters);
this.processInstanceId = processInstance.getId(); 
((ProcessInstanceImpl) processInstance).setMetaData("ParentProcessInstanceId", processInstance.getId()); // note: wrong process instance id


You can try to read the property +processInstanceId+  from class or build your own logic.
