<b>Description.</b><br/>A <b>Allocation</b> describes which amount of a <b>Product</b> or <b>Produce</b> is transferred from a source to a destination.<br/><br/><b>Remark.</b><br/>In many cases an amount of Product or Produce  will be transferred from a certain Batch into an other <b>Batch</b>, but in case of harvesting it can originate from a certain <b>TreatmentZone</b>. In case of product application, the source is a Batch and the destination is the TreatmentZone. <br/><br/>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 <b>Processor</b>.<br/><br/><b>Example.</b> <br/>The allocation can be an amount of Produce originating from a TreatmentZone ( tr1) during harvesting, which ends up in a grain tank on the harvester (the Batch batch 1). tr1 is the strips that are harvested for that grain-tank. This grain-tank load (batch 1) can be put in a trailer (batch 2). A next grain tank load (batch 3) harvested from the strips forming the next TreatmentZone tr2, can be added to the trailer ( still batch 2, now connected to two instances of Allocation). The trailer (batch 2) can be put in a grain storage (batch 4).<br/>
