I have a large product structure with multi level parent child relationship, where 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 all the product and requirements at once?

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