We have created group product via "test group product" and it has 4 associated item.
When we create sales order using group product we choose 3 products from associated products.
When we fetch the order through API, we get the products array for each product and product_type="grouped". But there is no other parameter which tells us that the given product is associated with which parent product. Because all the parent_item_id are blank so we cannot determine to which parent product the group product is associated?
So how can we determine the parent product name?
