Salesforce 代碼鎖定記錄

需要在“流程自動設置“中 選擇在Apex 中啓用記錄鎖定和解鎖複選框

global class LockAndUnlock {
  //訂單鎖定
    WebService static void lock(Id OrderId){
      List<MicroPowderOrder__c> orderList = [Select Id from MicroPowderOrder__c where Id = :OrderId];
      Approval.lock(orderList, false);
    }

    //訂單解鎖
    WebService static void unLock(Id OrderId){
      List<MicroPowderOrder__c> orderList = [Select Id,OrderStatus__c from MicroPowderOrder__c where Id = :OrderId];
        for(MicroPowderOrder__c mpo : orderList){
            mpo.OrderStatus__c = '草稿';
        }
        update orderList;
      Approval.unlock(orderList, false);
    }
}
