MaterialPackageBatchId Property

There is material in the factory where not each material unit is identifiable. This is the case for Trays for example. Trays are delivered as a batch of trays. But each tray does not have a unique ID, only the batch of trays has a unique ID. In this case, we assume that the unique Batch ID is in the property BatchID and each tray which is been mounted will get a temporary UniqueIdentifier as long as it is been mounted on the machine. See BatchMaterialPackage for more details.
