We being an FMCG Industry dealing various fast moving goods we intended to implement product hierarchy. Accordingly apart from Standard 3 levels we upto 9 levels and this helps to map our product to the way we want to map. Eg. Sports and Food are two types of products dealt with. Food can be further drilled down to Masalas and further split up to Veg and Non Veg Masalas.
You need to create data element for additional levels where there is a slight customization. Rest of the things are so easy.
Each and every level has to be created and saved and then based on the preceding level next level is to be created.
Earlier, this has been tried with material grouping to a smaller level and now product hierarchy supports to classify the product as we need.
Yet another proof of the excellent features of SAP.
