When I try to delete a Warehouse Shipment, I get this error:
You cannot delete the shipment because a ZenKraft shipment has been created.
A ZenKraft shipment was created. You'll need to delete the ZenKraft shipment first from the related list "Shipments" on the Warehouse Shipment page. Then, you should be able to delete the Whse. Shipment.
If the ZenKraft shipment has already been deleted and you still get the error, the ZenKraft Shipment Created field on the Whse. Shipment needs to be unchecked.
