Now it is possible to create a hierarchy in the product catalog with as much levels in your pyramid as you want.
The info is all stocked in the hierarchy path field however this is a read only atrribute so this information cannot be used afterwards.

it would thus be nice to also have the possibilty to get the parent of a parent record on a product for example.
because sometimes you have a product with same name however comming from a different product family and with only the possibilty to get parent info on this record its not enough
also it would make it easier to split reporting over product families/..
