Product: Sage X3
Issue: When attempting to export out an inbound Purchase Order (850) from your Trading Partner you receive the following error: 'xxx Non-existent Product on this site xxx - Error Field error [M:SOH4]QTY'
Reason: The Item Code you're attempting to pass to Sage X3 on this order is not a valid item based on the Shipment Site that was provided.
Solution - Correct Site Product
You'll need to work with your Sage X3 system's team to properly add the item into the Shipment Site you've configured with Transaction Manager if you wish to receive orders for this item.
This is outside of TrueCommerce Support as TrueCommerce does not maintain your Inventory
