Overview
Whenever a material lot auto creates a new lot number, the CreateLotNumber event is fired. You can use this event to intercept the generation of lot numbers so that the format of the lot number or even the number itself can be modified. For systems that retrieve lot numbers from a ERP or other system, this event will allow obtaining a lot number from it. Script in this event can also read from a block of available lot numbers that are maintained in a database. This example will explain how to generate a lot number through scripting.

Scripting Examples
Code |
#Here is how to get the primary event object:
materialLot = event.getMESObject() # Lot number is set as Name property -> materialLot.setName("ABC12345")
lotName = 'A-' + str(system.date.toMillis(system.date.now()))
materialLot.setName(lotName)
#To properly implement this function, it must either set or return the result as shown below:
event.setResult(True)
#return True |
Generate Lot Number for a specific Material
Code |
#Here is how to get the primary event object:
materialLot = event.getMESObject() # Lot number is set as Name property -> materialLot.setName("ABC12345")
materialDef = materialLot.getMaterialDefLink()
materialName = materialDef.getName()
if materialName == 'Material A':
lotName = 'A-' + str(system.date.toMillis(system.date.now()))
else:
lotName = 'B-' + str(system.date.toMillis(system.date.now()))
materialLot.setName(lotName)
#To properly implement this function, it must either set or return the result as shown below:
event.setResult(True)
#return True |
