  • You need to insert new work parts records for each inserted new case record.
    Following is the code of helper class:
    public class MaintenanceRequestHelper {
    public static void updateWorkOrders(Map cOldMap, Map cNewMap){
    List caseToProcessIdList = new List();
    Map> caseIdToWpMap = new Map>();
    Map insertCaseMap = new Map();
    Map> insertWpMap = new Map>();
    List insertAllWpList = new List();
    Integer commonKey = 0;
    for(Id csId : cNewMap.keySet()){
    if(cOldMap.get(csId).status != 'Closed' && cNewMap.get(csId).status == 'Closed' && (cNewMap.get(csId).type == 'Repair' || cNewMap.get(csId).type == 'Routine Maintenance'))
    if(caseToProcessIdList.size() == 0)
    for (Work_Part__c wp: [Select Id, Name, Equipment__c, Equipment__r.Maintenance_Cycle__c, Maintenance_Request__c, Quantity__c From Work_Part__c Where Maintenance_Request__c IN :caseToProcessIdList]) {
    caseIdToWpMap.put(wp.Maintenance_Request__c, new List{wp});
    List tempList = caseIdToWpMap.get(wp.Maintenance_Request__c);
    caseIdToWpMap.put(wp.Maintenance_Request__c, tempList);
    for(Id csId : caseToProcessIdList){
    List relatedWpList = caseIdToWpMap.get(csId);
    List insertWpList = new List();
    Integer minDays;
    if(relatedWpList==null || relatedWpList.size()==0){
    relatedWpList = new List();
    minDays = 0;
    for(Work_Part__c wp : relatedWpList){
    if(minDays == null || minDays >= wp.Equipment__r.Maintenance_Cycle__c.intValue())
    minDays = wp.Equipment__r.Maintenance_Cycle__c.intValue();
    insertWpList.add(new Work_Part__c(Equipment__c=wp.Equipment__c, Quantity__c=wp.Quantity__c));
    Case oldCase = cNewMap.get(csId);
    Case cse = new Case();
    cse.Type ='Routine Maintenance';
    cse.Status ='New';
    cse.Origin =oldCase.Origin;
    cse.Vehicle__c = oldCase.Vehicle__c;
    cse.Equipment__c = oldCase.Equipment__c;
    cse.Subject = String.isBlank(oldCase.Subject) ? 'subject' : oldCase.Subject;
    cse.Date_Reported__c =;
    cse.Date_Due__c = System.Today().addDays(minDays);
    insertCaseMap.put(commonKey, cse);
    insertWpMap.put(commonKey, insertWpList);
    insert insertCaseMap.values();
    for(Integer i : insertCaseMap.keySet()){
    for(Work_Part__c wp : insertWpMap.get(i)){
    wp.Maintenance_Request__c = insertCaseMap.get(i).Id;
    insert insertAllWpList;
