Once you have created attributes in the Attributes sub-module (for more information about this sub-module, see Attributes Sub-Module Overview), you can assign them to items. In this section of the Variations tab, you can assign those attributes to the item you are adding/editing (1), and you can create variations based upon those attributes (2).
The first step to creating a variation for an item is assigning attributes to the item using Item Attributes (1). First, you will select an attribute from the drop-down list (A). You can either select an existing attribute from the Attributes sub-module or create a custom attribute for this particular item. In order to add your selection to the item, click the Add button (B) (if creating a custom attribute, input it into the window that pops-up and click OK). Below the drop-down list the name of the attribute you have added will be listed (C). To select which values of that attribute apply to the item, type them into the Values search field (D) (for a step-by-step guide showing you how to add these values, see Setting Up Item Variations in coreSTORE).
You can also remove the attribute from this item by clicking Delete (E). If you need to add an attribute that you also want to use for other items or to add a value to an existing attribute, you can access the Attributes list by clicking Manage Global Attributes (F) (for more information, see Attributes Sub-Module Overview).
After assigning attributes to the item, use Item Variations (2) to create variations based upon those attributes. The easiest way to create variations is to click the Auto create variations button (G), which will automatically create variations based upon the attributes and values added in Item Attributes (1).
You can also create variations on your own. To add a variation click Add Item Variation (H), then input a name for the variation (J), select which attribute the variations correlates with (K) (for a step-by-step guide showing you how to select the attribute, see Setting Up Item Variations in coreSTORE), input the item number that corresponds to the specific item with the variation (L), and select from the drop-down list (M) if the variation is an Ecommerce item (Yes or No). When you create each variation, coreSTORE will automatically assign it a Variation ID (N). To delete a variation, click Delete (O).
(Note: Once you have created the variation, you can manage pricing and inventory per variation.)
