Background

sometime you cannot store the file directly ,maybe there are another process are reading/storeing the file , so you would need to wait another proecess done and retry . then we come up this solution .

有时您不能直接存储文件，可能还有另一个进程正在读取/存储文件，所以您需要等待另一个过程完成并重试。然后我们提出了这个解决方案。

mind : add a while true loop , try store the file , if error then sleep 2s and retry till completed .添加一段真循环，尝试存储文件，如果错误，然后睡眠2s，重试直到完成。

ErrorMode

参数	说明
ErrorMode=1	默认设置。脚本执行会暂停，并且会提示用户进行操作（非批量模式）。 The default setting. The script execution will halt and the user will be prompted for action (non-batch mode).
ErrorMode =0	Qlik Sense 只需忽略故障，并继续在下一个脚本语句上执行脚本。 Qlik Sense will simply ignore the failure and continue script execution at the next script statement.
ErrorMode =2	一旦出现错误，Qlik Sense 会立即触发“脚本执行故障...”错误信息，但不会提示用户预先进行操作。 Qlik Sense will trigger an "Execution of script failed..." error message immediately on failure, without prompting the user for action beforehand.

Sleep

Argument	Description
n	Stated in milliseconds, where n is a positive integer no larger than 3600000 (i.e. 1 hour). The value may be an expression. 以毫秒为单位表示，其中 n 是一个正整数，且不得大于 3600000（即 1 小时）。该值也可以是一个表达式。
