Categories Product Amount shown as 0 in admin

[VladyslavSikailo]

Preconditions and environment

• Magento or Adobe Commerce 2.4.8-p3
  • with ACSD-67643 quality patch installed
  • Or with this commit applied dba0f6f

Included quality patch content: ACSD-67643_2.4.8-p1.patch

Steps to reproduce

• Create 401 categories or set the value of \Magento\Catalog\Model\ResourceModel\Category\Collection::BULK_PROCESSING_LIMIT to 1
  • Changing BULK_PROCESSING_LIMIT is needed to emulate a big catalog, so Magento runs a special mechanism (using a temporary table) to retrieve product count per category. This specific mechanism has a bug.
• After creating products and categories, ensure all categories are anchors by running: UPDATE catalog_category_entity_int SET value = 1 WHERE attribute_id = (SELECT attribute_id FROM eav_attribute WHERE attribute_code = 'is_anchor');
• Open categories page in admin
• Open any category without children
• Assign any product to this category
• Reload page

Expected result

• This category must have (1) as product count in a left bar with categories list

Actual result

• The category has (0) as product count in a left bar with categories list

Additional information

• This happens because of the quality patch ACSD-65848 installed
• It contains commit dba0f6f which removes OR ce2.entity_id = ce.entity_id from SQL Select Query
• So categories without child categories won't be included in SQL Select

The obvious fix is to include categories without children and use insert ignore to prevent duplications:

However, we must double-check the issue from https://experienceleague.adobe.com/en/docs/commerce-operations/tools/quality-patches-tool/patches-available-in-qpt/v1-1-71/acsd-67643 and make sure it's fixed

Thanks.

Hey @engcom-Bravo
Do you have more than 400 categories? Or have you adjusted \Magento\Catalog\Model\ResourceModel\Category\Collection::BULK_PROCESSING_LIMIT?

Upd: now I also see that steps to reproduce from https://experienceleague.adobe.com/en/docs/commerce-operations/tools/quality-patches-tool/patches-available-in-qpt/v1-1-71/acsd-67643 might be the steps that we need here

Upd2: After creating products and categories, ensure all categories are anchors by running: UPDATE catalog_category_entity_int SET value = 1 WHERE attribute_id = (SELECT attribute_id FROM eav_attribute WHERE attribute_code = 'is_anchor');
