def customfield_NAME = "custom field name"

void setField(String customfield_NAME){
    def issue = event.issue as Issue
	def customFieldManager = ComponentAccessor.getCustomFieldManager()
	def tgtField = customFieldManager.getCustomFieldObjects(issue).find {it.name == customfield_NAME}
	def cFieldValue = issue.getCustomFieldValue(tgtField).toString()
    def newcFieldValue = cFieldValue.toLowerCase()
    def changeHolder = new DefaultIssueChangeHolder()
	tgtField.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(tgtField), newcFieldValue),changeHolder)  
}

    setField(customfield_NAME);
