As the numbers of online customers are increasing so the numbers of shopping sites are also increasing with the time. When there are a lot of options available for a customer to purchase then why would he purchase from your store. Ease of shopping feature can attract customer to your store. Here ease of shopping refers to multiple factors like variety in product size, color, variant, easy checkout process and many more. Like traditional way of shopping customers buy items and often discriminate based on its color or other attributes, same is observed with online shopping. Magneto provides the functionality to facilitate such shopping environment; this makes Magento the most popular ecommerce platform. Configurable Product is one of the ways Magento offers to cater these requirements. Due to this customer can select their desired variant of the product without having to browse numbers of product pages. SKU (stock keeping unit) is an identification, usually alphanumeric which is assigned to each product that allows it to be tracked for inventory purposes. While saving a configurable product with big length SKU a fatal error is observed
