Create Supplier Quotation through Supplier Portal

In ERPNext, Supplier Quotations can either be created manually or via the Supplier Portal. Suppliers can create Quotations via the Supplier Portal once they have logged into the system. For this, the Supplier must be a registered Website User having the role of "Supplier".
For a Supplier to create a Quotation, there should be an existing Request for Quotation (RFQ) against them. To do this entire process, follow the following steps:
1) Create a Request for Quotation for the Supplier in the system. For example, we are creating an RFQ for "MNO Suppliers".

2) Now, the Supplier (MNO Suppliers in our case) has to log into the Supplier Portal using their login credentials. There, the Supplier will be able to view the RFQ
The Supplier has to enter the Item Rate and submit the RFQ.

Once the RFQ is submitted, a Supplier Quotation gets automatically created in the system against this RFQ. Click on the "View" option.

Observe that the Supplier Quotation is in the Draft state. After reviewing the Supplier Quotation, the user can submit it. This will also be reflected in the Supplier Portal.
