Sync Items Manually button:
Every 6 hours, our app automatically synchronizes new items from your WooCommerce store, however, if you want to import new items before that, simply click on the Sync Items Manually button, and refresh the page after some time ~ (5 - 10) minutes.
By default, our app will automatically map SKUs between your WooCommerce store and NetSuite SKU, if they are the same. In case, they are different, then you will have to map them manually by entering their NetSuite SKUs in the NetSuite SKUs empty field, further, click on the Submit button.
Note: Automatic mapping will be done based on this "NetSuite Item Mapping Field" setting and you can configure it from the Configuration page.
