To Fetch Related records field Value which has more than two levels

I am having Queue which holds orders. I want order related opportunity and Account fields on queue view.  

I created a view which has order, order related opportunity and account fields for my private queue. I am not able to get related opportunity and account fields data. 

I created some fields in queueitem and tried to fetch opportunity and account fields through workflow which triggers on queueitem creation but, this also did not fetch data, because two level of hierarchical fetching is not supported in workflow.   

Hi floks, help me to solve this issue.
