Rule

Changed on:

12 Aug 2025

Overview

Update an Aggregate Virtual Position and calculate its Available-to-Sell (ATS) quantity.Aggregate Virtual Position ATS calculation is based on the associated Inventory Positions Stock on Hand (SOH) quantities and the applied Controls.The associated Inventory Positions are defined with:

The given Product Reference
The list of Locations for the given Network (the first Network assigned to the Virtual Catalog)
The specified Inventory Position Statuses

Plugin Name	Inventory Reference Module
Namespace	[[account.id]].globalinventory

The Inventory Reference Module is the foundation for inventory related implementations. It provides reference Workflows for inventory ingestion and processing. Extensible by design, use this Module as a base to build a solution to the needs of your customers.The Inventory Module includes the following areas:

Product Catalogue workflow
Inventory Catalogue workflow
Control Group workflow
Virtual Catalogue workflow

Inventory Reference Module

Product Catalog workflow
Inventory Catalog workflow
Control Group workflows
Virtual Catalog workflows

UI Description

Updates an aggregate virtual position including inventory positions in the given {statuses}.

Accepts

VIRTUAL_POSITION

Actions

This Rule produces a MutateAction that updates the target Aggregate Virtual Position ATS quantity.

This Rule throws an `EventAttributeNotFoundException` when the required Event attribute(s) is not provided.

Configuration example

1{
2  "name": "[[account.id]].globalinventory.UpdateAggregateVirtualPosition",
3  "props": {
4    "statuses": [
5        "ACTIVE",
6        "AT_RISK",
7        "OUT_OF_STOCK"
8    ]
9  }
10}

Detailed Technical Description

This Rule performs the following steps during execution:

Retrieve Contextual Data
- The Rule extracts the Aggregate Virtual Position and associated Catalog data from the Event attributes.
Determine Relevant Inventory Positions
- The Rule identifies Inventory Positions that contribute to the Aggregate Virtual Position being updated.
- It loads a list of Location References from the Network linked to the specified Virtual Catalog. Only the first Network from the `virtualCatalogueNetworkIds` event attribute is considered.
- It queries Inventory Positions using the following criteria:
  - The Inventory Catalog Reference from the `virtualCatalogueInventoryCatalogueRef` Event Attribute
  - The Product Reference from the `virtualPositionProductRef` Event Attribute
  - The list of Location References obtained in the previous step
  - The Inventory Position Statuses specified by the Rule's `statuses` parameter
Recalculate ATS Quantity
- The Rule calculates the updated ATS (Available to Sell) quantity for the Aggregate Virtual Position.
- This is based on the total SOH (Stock on Hand) from the matched Inventory Positions, applying any relevant Controls.
- If no Controls are present, the ATS is simply the total on-hand quantity.
- The calculation logic is identical to that used in the CreateAggregateVirtualPosition Rule and is described in the section below.
Update the Aggregate Virtual Position
- The Rule produces a MutateAction to update the existing Aggregate Virtual Position with the newly calculated ATS quantity.

Aggregate Virtual Position Available-to-Sell (ATS) quantity Calculation Algorithm

Determine the relevant Controls for the Aggregate Virtual Position:
- Load the list of Categories for the Variant Product (returns only the first 10) by:
  - The given Product Catalog Reference (`virtualCatalogueProductCatalogueRef` Event attribute)
  - The given Product Reference (`productRef` / `virtualPositionProductRef` Event attribute)
- Query Controls by:
  - The given Product Reference (`productRef` / `virtualPositionProductRef` Event attribute)
  - The loaded (in the previous step) list of Categories
  - The loaded list of Location References (from the first Network assigned to the given Virtual Catalog)
Apply the `EXCLUSION` Control.
- Exclusion Control types available:
  - Category Exclusion
    Control Reference naming convention: `{controlGroupRef}:EXCLUSION:{categoryRef}`
  - SKU Exclusion
    Control Reference naming convention: `{controlGroupRef}:EXCLUSION:{productRef}`
- The Aggregate Virtual Position ATS quantity is set to zero if an Exclusion Control with `ACTIVE` Status matches the Aggregate Virtual Position by Product or Category References
If no compatible Exclusion Controls have been found, apply the `QUANTITY_BUFFER` Controls to the Inventory Positions' SOH quantities:
- Get the relevant Buffer Controls with `ACTIVE` Status
  The following types are available:
  - Category Buffer
    Control Reference naming convention: `{controlGroupRef}:QUANTITY_BUFFER:{categoryRef}`
  - SKU Buffer
    Control Reference naming convention: `{controlGroupRef}:QUANTITY_BUFFER:{productRef}`
  - Location Buffer
    control ref: naming convention: `{controlGroupRef}:QUANTITY_BUFFER:{locationRef}`
  - SKU - Location Buffer
    Control Reference naming convention: `{controlGroupRef}:QUANTITY_BUFFER:{productRef}:{locationRef}`
- Sort the retrieved Controls by `executionOrder` in ascending order
- Apply only the first Buffer Control (compatible with a particular Inventory Position) to the SOH quantity
  Buffered SOH = SOH + Buffer value
- Set the Buffered SOH quantity to zero if it results in less than zero value after the Buffer application
Calculate the Aggregated Buffered SOH quantity for the Aggregate Virtual Position.
Aggregated Buffered SOH = IP1 Buffered SOH + IP2 Buffered SOH + ... + IPN Buffered SOH (IP 1,2,...,N stands for the Inventory Positions associated with the target Aggregate Virtual Position)
Apply the `MASTER_BUFFER` Control:
- Get the relevant Master Buffer Control with `ACTIVE` Status
  - SKU Master Buffer
    Control Reference naming convention: `{controlGroupRef}:MASTER_BUFFER:{productRef}`
- Calculate the Aggregate Virtual Position ATS quantity
  ATS = Aggregated Buffered SOH + Master Buffer value
- Set the ATS quantity to zero if it results in less than zero value after the Master Buffer application

Version History

v2.2.1

Rule changes:

Now apply control-specific logic only if the event includes a Control Group reference.
Skip all control-related validation and logic if no such reference is present in the event payload.
