Retrieve material requirement based on BOM, for open Sales Orders

Lovely people and experts of ERPNext, I would like to retrieve the following information:

For open Sales Order items, the products which got a Bill Of Material, I would like to see what the requirement is for those materials on end-level through the BOM. Is there something in ERP Next?

I guess I could write a query on the Mysql, but given this would be a, somewhat, complex query, I was hoping there is something available for this purpose?
