Hi,As you know better than me, the variant when managed identifies a different article in all respects, so both from a logistical and planning point of view, I believe that the ABC classification must be done for variant.Following Nabil's idea, the result could be stored on the ItemCoverage since in addition to the site and warehouse I would also have the item dimensions. It is clear that the calculation engine should be updated to calculate based on the item coverage. Alternatively, the InventDimCombination could also host the values ​​for the variant.
