I want set line item status that if a line item is delivered. In an order, order status is for all the items but line item status is for each product.
Is there any module or something in UI?
I am using drupal commerce module.
You can try using Commerce Delivery module... It supports line items delivery status..
Project page says
Provides basic functionalities and admin pages to handle deliveries.
Each delivery need to be associated to an order. Each order can have zero, one or multiple deliveries.
A delivery is automatically created on order save if it contains at least one shippable item. Further deliveries can be manually added from the deliveries tab under the orders menu. On the same page each order line item can be moved from one delivery to the other.
