# Identification of related products Relations are everything that connect one product to another. They may be a product relation attribute, or they may be used as children in grouping products, or they may be variants of other main products. ## Product relation attribute First, determine if there are any product relation attributes in the system. Go to **Product Design > Attributes** and double-click on the cell just under the **Type** field. This will open a list of all available attribute types.

Find the **Product Relation** attribute and select it. Then press **OK**.

Product Design > Attributes > Filtering by type

This action will filter out all Product Relation type attributes that are created in the system. Then, look for these attributes in the product (Product > Catalog) of the product you want to delete. Clear their values and save the changes. You may also add those attributes to the product catalog grid as described [HERE](https://usermanual.ergonode.com/products/catalog/system-views/custom-views) and work from there. {% hint style="info" %} Keep in mind that a different product may have a relation (value in the attribute) that relates to the product you wish to delete. {% endhint %} To check for this, drag the product relation attribute to the product catalog grid and search for the SKU of the product you want to delete. The filter will return only those products that have relations to the one you’re interested in.

## Grouping product The relation can be built by connecting products as **children** of a main **grouping product**. To easily find out if a product you wish to delete is connected this way, follow the same method as described earlier. Add the system attribute **Product Children** to the product catalog grid, and look for the SKU of the item you want to delete.

## Variable products The same approach applies to variable products. Add the system attribute **Product Variants** and search for relevant connections.
