I want to add Item Name in Supplier portal

Please provide the Solution for the item name shown in the Supplier portal

In the standard ERPNext Supplier Portal RFQ template, the item display is controlled by rfq_items.html, which calls the item_name_and_description() macro.

Your macro currently may be like

{{ d.item_code }}

<p class="text-muted small">{{ d.description }}</p>

You can change it as below :

{{ d.item_name }}

<p class="text-muted small">{{ d.description }}</p>
