MDVA-30112 Magento patch: large number reservation inconsistencies

The MDVA-30112 Magento patch solves the issue where you have an unexpectedly large number of reservation inconsistencies in the inventory_reservation table. Reservation inconsistencies include unregistered open orders and complete orders that are not registered. This patch is available when the Quality Patches Tool (QPT) v.1.0.8 is installed. Please note that the issue will be fixed in Magento version 2.4.2.

Affected products and versions

• The patch was designed for Magento Commerce Cloud 2.3.5.
• The patch is also compatible with Magento Commerce and Magento Commerce Cloud 2.3.4 - 2.3.5-p2, 2.4.0 - 2.4.1.

Note: the patch might become applicable to other versions with new QPT tool releases. To check if the patch is compatible with your Magento version, run ./vendor/bin/magento-patches status .

Issue

The bunch-size value is the value for how many orders to load at once. When there are more orders than this value, Magento considers the orders with pending status to be inconsistencies.

There is a patch MDVA-33281 that fixes three other inventory inconsistency issues. This includes a PHP Fatal error when running bin/magento inventory:reservation:list-inconsistencies in the CLI. Another issue that is fixed is duplicate data in the inconsistencies list. Also, the issue where a reservation is created before order placed (previous realization based on reservation after order placed). For the solution, refer to MDVA-33281 Magento patch: inventory inconsistency issues .

Prerequisites: You run the following command in the CLI to list reservation inconsistencies in the inventory_reservation table:

magento inventory:reservation:list-inconsistencies

You see an unexpectedly large number of reservation inconsistencies and/or the command never completes.

Steps to reproduce:

1. Run the following command in the CLI to resolve the inconsistencies: clike bin/magento inventory:reservation:list-inconsistencies -r | bin/magento inventory:reservation:create-compensations
2. Place three orders:
   • Assign each a single product.
   • Use the Check/Money Order payment method, so the order status will be "pending".
3. You can see three records with -1 quantity in the inventory_reservation table. Run the following command in the CLI to see any inconsistencies: clike bin/magento inventory:reservation:list-inconsistencies

This returns no results, which is correct.

1. Run the following command in the CLI: clike Execute bin/magento inventory:reservation:list-inconsistencies --bunch-size 1

You see the "pending" status orders are shown as inconsistencies.

1. Run the following command in the CLI: clike bin/magento inventory:reservation:list-inconsistencies -r --bunch-size 1 | bin/magento inventory:reservation:create-compensations

Expected results:

Magento should not resolve inconsistencies of "pending" status orders. The stocks inconsistencies should be resolved for orders with 'complete', 'closed', and 'canceled' statuses.

Actual results:

When there are orders more than the specified bunch-size value, Magento considers orders with "pending" status as inconsistencies and Magento adds multiple inconsistency resolving records for same order.
