"While Supplies Last" is an option on a Packing Rule that prompts the addition of an item to an order. If a rule-qualifying item is out of stock, orders can be shipped without the items added as part of the rule.
To accomplish this, set your Packing Rule as follows:
1. Select the "Customer" dropdown and click on "Rules".
2. Click on the tab titled "Packing Rules".
3. Click on "Create Packing Rule" to create a new Rule or click "Edit" on an existing Rule.
4. Enable "Only suggest this item while there's sufficient inventory?" and then click "Save Rule".
When "Only suggest this item while there's sufficient inventory?" is enabled, you will see that the rule displays the verbiage "While supplies last" on the dashboard:
The implications for "While Supplies Last" are slightly different based on the type of Rule.
Since Routing Rules are evaluated when an order is created, the inventory level may change by the time the order is shipped. This means:
If the item is promised to the end customer, was in stock when they ordered, and is now out of stock, the order will be held until the item is in stock.
If the item is unexpected by the end customer and was in stock when they ordered, but is out of stock when the order shipped, the order would be held.
Packing Rules are evaluated at the time of shipment. If "While Supplies Last" is enabled, the item will only be suggested if it's in stock.
