<ul>
<li><strong>Replace SKUs<br />
</strong>Replace your existing SKU with a new one. If there is no SKU to replace, the extension won’t add a new SKU.</li>

</strong>This rule type will assign an additional SKU to products, regardless of whether they already have an SKU or not.</li>
<li><strong>Product with no SKUs<br />
</strong>Add SKUs to products with no SKU only. If the SKU is already present in any of the selected products, the rule will not add an SKU for that product.</li>
</ul>

<h2>Customize SKU length for consistency</h2>

<h2>Flexible product SKU format options</h2>
<p>The SKU format can be easily personalized by adding any custom text anywhere in the field along with the predefined variables.
