From a data model perspective, the Customer hierarchy and the Product hierarchy are two different things. So you must load them in different fields. Then you can make the table you want. See attachment.

thanks for your answer. Unfortunately, your solution is different of what I need. The Hierarchy concerns only customers.
In fact, we negociate with holding a list of product. The products must after negociation be sold in every shops of the hierarchy. That's what we want to analyze.
With your proposal, we are able to see customer hierarchy H1 and product hierarchy H2 alltogether. What I only want to see are the products listed in each hierarchy, and not those which are not listed.
