# How do I change the quantity only for specific stock levels (e.g., change 1 to 2)?

To change quantity only for specific stock values in your feed (for example, update all products with a supplier quantity of **1** to **2**), you can use **Quantity Rules** in the Quantity field settings.

Steps:

1. Open your Update Feed.
2. Go to **Field Mapping → Quantity → Smart Settings**.
3. Scroll to **Quantity Rules** and add a new rule.
4. Set the condition: **Equal → 1**.
5. Set the Result/Quantity to **2**.
6. Save and run a **Preview Sync** to confirm the changes before running the full sync.

This rule updates only products with a quantity of **1**, without affecting other quantities (such as 0 or higher values).
