The following terms are used extensively when talking about the ProductCart Apparel Add-on.
Sub-Products
Inventory parts that are generated by combining the Attributes included in the Option Groups assigned to an Apparel Product. The total number of Sub-Products that ProductCart generates for any given Apparel Product is the result of the following formula:
Number of Sub-Products = Option Group 1 Attributes * Option Group 2 Attributes * Option Group 3 Attributes * …
E.g. If an Apparel Product has been assigned the colors “Red”, “Blue”, and “Yellow”, and the sizes “Small”, “Medium”, and “Large”, ProductCart will generate 9 Sub-Products.
