We have a problem to separate the defect item from the normal item.
Example we have 100 items, if we 'stock in' these 100 items to the system, we can choose either to make it available on the web or not (as it's a product, not a variant)
But after the QC, we found out 10 variants are defected and we still manage to sell those with the lower price(the return cost is higher, that's why)
However, we don't want to sell them on the web because the item needs explaination before somebody purchase that. We only need those variants to available in POS but in the same product.
We did tried to create another 'Product' and put all the defects in the different variant, but maximum only 100 variants can be added.
