设置项

说明

详细设置

运行计划的名称,将显示在运行计划列表中。

执行方式

可选择执行一次或定时执行。

如需设置自动单次运行计划,则选择执行一次

如需设置自动定时刷新数据,则选择定时执行

选项

可选追加数据覆盖两种数据更新方式。

追加数据:追加时不改变原来的数据,仅追加新的数据。

覆盖数据:使用新数据替换掉原来的数据。

无论是追加还是覆盖,都要求新的数据表结构与原 Excel 完全一致,包括数据表的列数,列名,数据格式等。

文件夹地址

用于抽取数据的文件夹地址。

请确保系统可以直接访问该地址,并且具有读写权限。

运行计划执行成功之后,会自动将文件夹中的文件删除。

使用模板

执行方式选择定时执行时才会出现此选项。

要于选择是否使用运行计划模板,如勾选则只能使用运行计划模板来创建运行计划;如果不勾选则可以进行自定义运行计划。

只有当执行方式选择为定时执行,管理员在后台管理中开启了允许用户创建自定义运行计划功能(详见系统外观中相关介绍),且有可用的运行计划模板,才会显示出使用模板复选框。

重复周期

执行方式选择为定时执行时才会出现此选项。

如不勾选使用模板,则需自定义运行计划的循环周期。

循环周期的定义方法与数据源运行计划模板一致,请参见模板中的介绍 数据源运行计划模板

开始时间

运行计划自动执行的具体时间,最快可设置为五分钟后执行。 当使用运行计划模板时,则自动设定为模板中设置的时间。

执行基准时区

选择计划执行的基准时区。

结束时间

当执行方式选择为定时执行时,用于设置计划的结束时间。

当使用运行计划模板时,则自动设定为模板中设置的时间。

消息通知方式

当数据刷新失败时,系统会向配置的邮箱或应用消息发送通知。

默认只能使用邮件通知方式进行发送,如果想要使用应用消息通知,需要在管理后台通知中心提前配置好应用程序(详见通知中心设置)。

注意:如需使用邮件通知,也请确认管理后台中的邮件设置正确,否则无法发送通知邮件。

4. 完成

设置完成后,即可在已有计划中看到刚刚设置的自动运行计划。单击右侧的image2021-4-30_16-46-14.png 可以编辑,禁用或删除运行计划

提示

数据源仅支持添加一个运行计划。

自动单次执行的运行计划在执行完毕后会自动删除。此时即可添加新的运行计划。

定时刷新示例

场景:

A公司每天都会产生一个 Excel 格式的销售数据文件,存放在文件夹 “E:\每天销售数据”中。

需求:

想要在 Wyn 中的数据源自动追加每天的新数据,保持数据源中一直为汇总数据。这样便可以直接进行后续的数据分析和展示使用。

实现分析:

此需求我们便可以通过 Excel 数据源的自动追加功能来实现,将自动追加的时间计划设置为每天一次即可。

实现步骤:

1. 使用第一天的数据创建 Excel 数据源。

提示

管理员在后台管理中开启了允许用户创建自定义运行计划功能后,用户在配置刷新周期时将出现使用模板的复选框。此时用户可以使用模板也可以进行自定义刷新周期。

如管理员未开启允许用户创建自定义运行计划功能,则仅能使用已有的刷新模板。

有关管理员如何允许用户创建自定义运行计划功能,请见门户外观设置中相关介绍。

5. 创建成功

6. 查看效果

运行计划执行后,可见已将第二天的数据追加上来。
