Publish inventory availability details

Adobe Commerce receives the inventory updates such as full sync and activity-based sync from IBM® Sterling Intelligent Promising Inventory Visibility, which is a hyper scaling, multi-active microservice and inventory controller for the Adobe Commerce integration with IBM Sterling Order Management System.

Orders that are placed with Adobe Commerce are fulfilled by Sterling Order Management System, and the inventory availability at the ShipNode level is published from Sterling Intelligent Promising Inventory Visibility to Adobe Commerce. The inventory availability information that is published from Sterling Intelligent Promising Inventory Visibility is used to refresh the cache in Adobe Commerce and the availability is displayed in the product details page.

The integration supports publishing of the inventory availability details from Sterling Intelligent Promising Inventory Visibility and not from IBM Sterling Global Inventory Visibility. The integration publishes the full availability snapshot from Sterling Intelligent Promising Inventory Visibility to Adobe Commerce.

Prerequisites

You must provision a separate IBM Cloud Object Storage bucket for each event to push the inventory availability details from Sterling Intelligent Promising Inventory Visibility to Adobe Commerce.

You must subscribe to events in Sterling Intelligent Promising Inventory Visibility and verify that the events are published to IBM Cloud Object Storage. For more information, see Event subscriptions.

You must map the source and stock levels in Adobe Commerce with ship nodes and distribution groups in Sterling Intelligent Promising Inventory Visibility. For more information, see Mapping for inventory details.

Agents for pushing inventory details

Inventory Publish, an asynchronous interface, uses the IAC_IV_INVENTORY_TRIGGER and IAC_IV_INVENTORY_PUBLISH agents to publish the inventory details from Sterling Intelligent Promising Inventory Visibility to Adobe Commerce.

You must set separate schedules in the Self Service tool to start the IAC_IV_INVENTORY_TRIGGER and the IAC_IV_INVENTORY_PUBLISH agent servers. Ensure that you schedule the servers to start at an interval of minimum half an hour.

For example, if you schedule IAC_IV_INVENTORY_TRIGGER to run daily at 12:00 AM, you might schedule the IAC_IV_INVENTORY_PUBLISH agent server for 12:30 AM. This is to ensure that the files are loaded into the IBM Cloud Object Storage bucket before they can be processed.

For more information, see Scheduling server processes on the next-generation platform.

IAC_IV_INVENTORY_TRIGGER
The IAC_IV_INVENTORY_TRIGGER agent run per the pre-defined schedule or on-demand and triggers the publish_all Sterling Intelligent Promising Inventory Visibility REST API for all the ShipNodes of Sterling Intelligent Promising Inventory Visibility. This API then publishes the ProductAvailabilityToSell.ShipNodeSnapshot events for all ShipNodes to the IBM Cloud Object Storage bucket.
IAC_IV_INVENTORY_PUBLISH
The IAC_IV_INVENTORY_PUBLISH agent reads the published files from the IBM Cloud Object Storage bucket, transforms the data into the Adobe Commerce format, and calls the Adobe Commerce Inventory Update API to publish the inventory availability status. The Inventory Update (Source-Items) API is called by using the Bulk asynchronous end point of Adobe Commerce.
```
http://<host>/magento2/rest/async/bulk/V1/inventory/source-items
```
For more information, see Bulk endpoints.
Note: The IAC_IV_INVENTORY_PUBLISH agent runs only in the full sync mode. For more information about the full sync mode, see Full sync mode.

Service for publishing inventory details

You must use the IACInventoryUpdate service to publish inventory details from Sterling Intelligent Promising Inventory Visibility to Adobe Commerce.

The IACInventoryUpdate service uses the IACValueMaps.xml to map ship nodes in Sterling Intelligent Promising Inventory Visibility to sources in Adobe Commerce.

You can customize the IACValueMaps.xml for mappings between Sterling Intelligent Promising Inventory Visibility and Adobe Commerce. For more information, see Configuring IACValueMaps.xml.

The IACInventoryUpdate service converts the Sterling Intelligent Promising Inventory Visibility messages to the Adobe Commerce messages and prepares the bulk payload. The total number of payloads in a bulk payload is based on the value set for the iac.integration.inventory.payloadinbulk.count property. The default value is 20. This service is used to make a REST API call to Adobe Commerce with bulk payload.
