In many cases an amount of Product or Produce will be transferred from a certain Batch into an other Batch, but in case of harvesting it can originate from a certain TreatmentZone. In case of product application, the source is a Batch and the destination is the TreatmentZone. In case of delivery to a third party, the destination batch might be out of the scope of the delivering party. In that case only a reference is made to the Processor.
