使用标签对50多个帐户执行executeInParallel

对于运行MCC级别脚本的人来说，最大的限制之一是 50个账户限制 由executeInParallel函数强加。直到最近，解决此限制的一种方法是 将已处理的帐户列表存储在Google云端硬盘上 并在需要时更新文件。

最近，AdWords脚本小组启用了 可以将标签应用于MccApp对象中的每个帐户。这样，我们就可以编写出更加清晰的脚本版本，该脚本使用标签指示何时处理每个帐户。使用这种方法并每小时运行一次此脚本，您每天最多可以处理1,200个帐户。

以下代码旨在为您提供一个框架，以替代您自己的MccApp代码。然后，您可以安排此代码每小时运行一次，它将继续处理您的MCC中的帐户，直到每个帐户都完成为止。

当有帐户返回错误时，它也会尝试通知您，以便您进行调查。关于此脚本的一个警告是，如果遇到Mcc级别（即结果功能）的超时限制，则可能不会将标签应用于每个成功完成的帐户。您可以通过用以下内容替换第76行并删除第89行来解决此问题：

applyLabelsToCompletedAccounts（[result.getCustomerId（）]）;

无论如何，我希望这会有所帮助，并让我知道您是否在评论中遇到任何问题。

谢谢，
