By default, the item quantity information that is displayed on your WebStore comes directly from RMS/RMH.
If items are currently out-of-stock, you can either exclude them from displaying on the WebStore or apply logic to display a message regarding their availability.
How to enable
1. In WebSell Sync Configuration, under Advanced, select Field Mappings.
2. Right-click on the Item table, then select Properties.
3. Replace the value in Filter Clause with the following:
| webitem=1 AND inactive=0 AND (quantity-quantitycommitted > 0) |
4. Click OK and synchronize your webstore.
