|  --- | --- | --- | --- | --- | --- |
| `type` | [`?string (InventoryChangeType)`](../../doc/models/inventory-change-type.md) | Optional | Indicates how the inventory change was applied to a tracked product quantity. | getType(): ?string | setType(?string type): void |
| `physicalCount` | [`?InventoryPhysicalCount`](../../doc/models/inventory-physical-count.md) | Optional | Represents the quantity of an item variation that is physically present<br>at a specific location, verified by a seller or a seller's employee. For example,<br>a physical count might come from an employee counting the item variations on<br>hand or from syncing with an external system. | getPhysicalCount(): ?InventoryPhysicalCount | setPhysicalCount(?InventoryPhysicalCount physicalCount): void |
| `adjustment` | [`?InventoryAdjustment`](../../doc/models/inventory-adjustment.md) | Optional | Represents a change in state or quantity of product inventory at a<br>particular time and location. | getAdjustment(): ?InventoryAdjustment | setAdjustment(?InventoryAdjustment adjustment): void |

| `measurementUnitId` | `?string` | Optional | The ID of the [CatalogMeasurementUnit](../../doc/models/catalog-measurement-unit.md) object representing the catalog measurement unit associated with the inventory change. | getMeasurementUnitId(): ?string | setMeasurementUnitId(?string measurementUnitId): void |
