By default, Manage Stock is set to No because the inventory of a configurable product is derived from the quantities of its associated simple products.

This section enables you to create simple products to associate to your configurable product.
To create a simple associated product:
The Copy from Configurable button works in a similar manner to the above, but it pre-populates many of the fields with information from the configurable product.
The Super Product Attributes box enables you to specify the Attribute Name that appears in the store for selection, and the price for each of the options. Two price options are provided: Fixed or Percentage.
The price for configurable products is a combination of the price from the Price Configuration. For example, if the configurable product’s price is $20 and the price for the Medium option is: Percentage and 10, then this variation of the product costs $22. The price of the associated products is not used for calculation.
