Extensiv Network Manager refers to products with multiple variations as Product Variations. Each variation is stored in Extensiv Network Manager as its own individual product with a unique Master SKU, which are then grouped together under what Extensiv Network Manager refers to as a Virtual SKU. Though each product can be managed separately through its Master SKU, the Virtual SKU allows you to update the Product Variationsas a group. In the example below, the virtual SKU is shown at the top and groups together three product variations.

If you want to make some changes to the variants, instead of opening each variant one-by-one, just click the virtual SKU, and you can then make the changes to the variants from the virtual SKU's record.
