Conditional Grouping in pivot table?

Hello,

please look at the attached file. Is there any way to make a conditional grouping?
In this specific case I would like to group all the product codes that have the same product code and sum their quantity in one row if the net purchase price is the same as well as with same sell price.
How to do it? Do I need to do it in pivot table, in data model, power bi or what?
Could you show me how it will be the best way?

Thank you very much in advance.
