It works for me, try this. I hope it helps.

function deepCloneStore (source) {
    var target = Ext.create ('Ext.data.Store', {
        model: source.model
    });
    Ext.each (source.getRange (), function (record) {
        var newRecordData = Ext.clone (record.copy().data);
        var model = new source.model (newRecordData, newRecordData.id);
        target.add (model);
    });
    return target;
}

Original source code reference.

You are trying to iterate store, instead you need to iterate store.data.items. And you do not need for cycle for record. Try this

var b = Ext.create("Ext.data.store"{
    model:'service'
});
Ext.getStore("a").data.items.each(function(record,id){
    //You can add multiple records by calling .add method once
    b.add(record.data.subServiceItems);
});

Write if this does not help.
