我正在尝试覆盖“NoteID”，基本屏幕标题表字段（Location我已经检查过了，并且正在为我工作。我希望下面的代码将帮助您

Hi Naveen，我已经检查了两次此代码，但当我单击“添加任务”按钮时，它仍然在“相关实体”字段中显示黑色值。在我的场景中，此代码工作不正常。您能建议我如何像这样覆盖此代码吗“添加提交更改或修改代码？？？。您好，Ashok，您试图在哪个屏幕中创建任务？能否请您向我们提供有关此问题的更多详细信息Hi Naveen，实际上我在客户位置（AR303020）屏幕中新建了“活动”选项卡，我正在使用该屏幕中的“添加任务”按钮添加任务（AR303020）屏幕，但它显示了“相关实体”字段的空白（您可以在上面的IMG示例中看到）。并且我重写该字段的也是[pxCaseNeNeNe]（消息，位置）[pxMelGeAdvices（方法= CyMeMyOD.AppEnter）]公共虚空洞定位-BbQueTythCaseEn附着（PXCask发送器）。{}[PXCacheName（Messages.Location）][PXFieldDescription][PXMergeAttributes（Method=MergeMethod.Append）]公共虚拟无效位置\u Location CD\u CacheAttached（PXCache sender）{}您好，请共享添加任务按钮代码好吗？
