D365: Workflow避免同一审核人多次审批(问题处理2：审批人拒绝，重新提交后，审批流直接流转到拒绝人节点)

前面提到过，当审批人出现在多个节点，前面的节点审批完成后，后面节点如果再次出现同一审批人，系统自动审批，在测试中发现另外一种场景，当审批流执行了多个节点后，中间节点的某个审批人拒绝了提交的单据，当用户再次提交审批流后，系统会出现新的bug，由于我们改过的逻辑，当审批流的工作项中出现了完成的记录，系统会自动跳过或者审批后创建的节点，这里没有考虑拒绝的情况，经过调查，按下面方法修复了此问题，修复后也解决了审批人拒绝，重新提交后，审批流直接流转到拒绝人节点，这个也是标准功能存在的缺陷。

代码也很简单，在处理工作项时，只需要加一个判断，判断当前的工作项的类型是否是WorkflowWorkItemType::WorkItem。

public static void removeWorkItems(WorkItemActivityContextCollection _workItems)

        boolean  skip;
        
        next removeWorkItems(_workItems);

        for (i = 0; i < _workItems.Count; i++)
        {
            workItemActivityContext = _workItems.get_ITEM(i);
            skip = SysWorkflowWorkItemHelper::skipWorkItem(workItemActivityContext);
