Troubleshooting Order Sync Failure Due to Backordered Items
NetSuite will allow an order to contain backordered items most of the time and NetSuite Connector can sync the order without a problem. The exception is if cash sales are being synced (typically done for Amazon FBA and Point of Sale orders) and the item is a lot-numbered item. In this case, an error is displayed informing you that to sync lot-numbered items on cash sales, you must have available inventory numbers in the specified location in NetSuite. Then, the SKUs that do not have inventory numbers are displayed.
The items listed in this error cannot sync because NetSuite is requiring a lot number on the inventory detail for those items. NetSuite Connector does not have lot number information. NetSuite Connector provides settings to automatically assign the first available lot to each item posted to sales orders and cash and cash sales. When you enable these settings, NetSuite Connector queries NetSuite for the first available lot number from the location being synced on the order item. But if NetSuite does not have inventory for that item in that location, then there is no lot information available. Therefore, NetSuite Connector cannot obtain the lot number from NetSuite to sync the items on the order.
To fix this error, you must add the inventory numbers of the corresponding items in NetSuite in the location that is being used for the sync.
