While a regular SKU represents a single item, such as a size medium blue shirt, a configurable SKU represents an object that is sold as a single item, but has variable components, such as a computer system or a car. Configurable SKUs are created the same way as regular SKUs, but you must select Configurable Sku from the Item Type drop-down menu in the New Item dialog box.
To create a configurable SKU:
Create an item of the type Configurable Sku. Example: Computer.
Create as many items of the type Configurable Property as you need. Configurable properties represent an individual aspect of the configurable item, such as Hard drive or RAM in our computer example.
To create a configurable property, go to Catalog Management > Catalog Elements. Select Configurable Property from the Items of Type drop-down list, then click the New Item button in the upper right.
Create as many items of the type Configurable Option as you need. Configurable options represent the individual options for a configurable property, such as 10GB SCSI hard drive from Company XYZ in our computer example.
Configurable options can be linked to an existing SKU. If linked to an existing SKU, the price you set in the configurable option overrides the SKU price.
To create a configurable option, go to Catalog Management > Catalog Elements. Select Configurable Option from the Items of Type drop-down list, then click the New Item button in the upper right.
Go back to the configurable property you created and add the configurable options to it.
Go back to the configurable SKU and add the configurable properties to it.
