Edit on GitHub
You are browsing a previous version of the document. The latest version is 202212.0.

The AvailabilityStorage module publishes all the availability information for abstract and concrete products. Items are grouped by abstract product, and the process is handled by Publish and Synchronize.

Published data example:

    "id_availability_abstract": 1,
    "fk_store": 1,
    "abstract_sku": "001",
    "quantity": 10,
    "SpyAvailabilities": [
            "id_availability": 1,
            "fk_availability_abstract": 1,
            "fk_store": 1,
            "is_never_out_of_stock": false,
            "quantity": 10,
            "sku": "001_25904006"
    "Store": {
        "id_store": 1,
        "name": "DE"
    "id_product_abstract": 1,
    "_timestamp": 1554886713.989162

This information is used on the product details page when Add to cart is rendered.

The events are triggered in these two cases:

  • Availability amount was 0, and now it’s more than 0.
  • Availability amount was more than 0, and now it’s 0.

By default, the product quantity does not affect the available or unavailable product state. Even though the events are triggered when the product quantity changes from 0 to N or from N to 0, it’s not the quantity change that triggers events, but the change of product status. You can change the default behavior for the events to be triggered whenever the quantity is changed. See HowTo - Change the default behavior of event triggering in the AvailabilityStorage module for details on how to do that.
