I have a large product structure with multi level parent child relationship, and the products are implementing requirements 
and i want to export all the requirements implemented to the product structure.
I tried exporting this with RFLP application , where i selected parent level product , did a smart open with RFLP but this method only brings me the requirements connected to the parent assembly , but i m unable to fetch all the sub level requirements connected to child .

Is there a method where i can export the full product structure and all the implemented requirements at once?

I have also tried using relations application , but the data is to large to navigate through each level using relations , not a feasible solution .
