M2.2.x: Fix the error that Pre Order function does not work with configurable product when config Use Flat Catalog Product/Use Flat Catalog Category

Created by Rosa Truong, Modified on Mon, 31 Aug 2020 at 07:51 PM by Rosa Truong

Issue: 

I installed the module version 1.1.5 on my Magento version 2.2.3. When config the child product of configurable product is Out of stock and Preorder set Yes/ When becomes out of stock, I found that on the product page, it does not show the Preorder button + Preorder message + Available Date.

Another thing, when setting all child products of configurable product is Preorder, the Preorder button does not show for the parent product.

How could you help to fix the issue?


Solution:

This issue is caused due to module Pre Order bug when config Use Flat Catalog Product Use Flat Catalog Category configurable product.

This issue only happens on Magento 2.2.x only since on Magento 2.3.x, it does not support Flat Catalog function anymore (https://docs.magento.com/user-guide/catalog/catalog-flat.html)

To fix this issue, we would like to give the hot-fix.
