# Combinations Export

For example if you have a product, a T-Shirt, with three versions Blue, White, Red, by default the module will export three individual products on CDiscount, three separate products.

On CDiscount, combinations are called “variants”. Your products have combinations that you want to export to CDiscount as variants; in the configuration of your [model](https://doc.common-services.com/en/article/configure-a-model-cdiscount-1h6nbx0/) you will find a “Variations/Combinations” section:

**Eligibility of products for this export**:

For your product to be eligible for the export, it must:

– Unconditionally, at least two attributes must be selected: **Color** and **Size**. If you miss one, the other or both, it does NOT work.

– The **Size** field mapping is mandatory. After configuring the model, you have to save the configuration and map the Size field in the [Mappings](https://doc.common-services.com/en/article/mapping-1xw5eq6/) tab.

– The category must authorize the variants:
  * in the model, level 3 often shows **“(is variant)”**
  * CDiscount typically accepts variants for Fashion, Sport and Jewelry products

**Configuration**:

Therefore, you select a field for the size, and one for the color.

In this example above, the Size field corresponds to the size attribute of the product sheet. These products have no color attribute, they are all white.

You can configure the combination as you like as long as both values are effective: size and color.

The mappings are applied to these fields: if you have configured a mapping in the appropriate tab, the Attribute or Feature field will be replaced in the export by the “mapped” value.

Each combination must also have a **unique reference** and an **EAN**: [Validate your catalog structure](https://doc.common-services.com/en/article/validate-your-catalog-structure-cdiscount-1trq16m/)

**Mandatory Information**:

Combination export always requires the fields **Gender** and **Audience Type**, and for the Sport category the **Main Sport** information, which you can fill in the Specific Data section.

If the mandatory fields are not filled, CDiscount could accept the feed, but then reject your products!
