If the stock items that you sell come in different types or sizes, you can set the details up from the Dimensions Setup window.
For example, a clothes retailer may sell trousers. These trousers will have different waist sizes, leg length and colour. Alternatively, a paint retailer will sell paint in different size tins in a variety of colours and in a variety of finishes. All of these dimensions can be set up here.
A dimension is broken up into four levels:
Dimensions. This is the main type of variant, e.g. colour.
Dimension breakup. This is the next level of your variant. If the main type is colour, the dimension breakup is a list of available colours.
Dimension sets. These are the groups the dimension is connected to.
