* **Update Inventory:** Allow Linnworks to submit changes in stock levels to AliExpress. Linnworks supports multiple stock locations for additional warehouses/fulfillment centers/suppliers. Ensure you set which Linnworks locations are used when submitting changes in stock levels to AliExpress via the [Location Mapping](https://docs.linnworks.com/articles/#!documentation/channels-location-mapping) screen accessed *Settings > Channel Integration.*
* **Max listed:** This specifies the maximum quantity that will be sent to the channel. For more details, go to the [Max Listed](https://docs.linnworks.com/articles/#!documentation/channels-inventory-updates/a/max-listed) guide.
* **Stock percentage:** This will send a percentage of the currently available stock level to the sales channel. For more details, go to the [Stock Percentage](https://docs.linnworks.com/articles/documentation/channels-inventory-updates/a/stock-percentage) guide.
* **End when:** This enables you to force the listing to end when the stock level gets to the specified amount, as opposed to the default value of zero. For more details, go to the [End When](https://docs.linnworks.com/articles/documentation/channels-inventory-updates/a/end-when) guide.
