When the page loads the onVisible function runs and populates the fields with the default values but I cannot get the Projects one to work. // true: populate collection with default values ForAll([6,5,4,3,2,1,0], Collect(colTimesheetDetails,{ 'Employee Email':varUser.Email, 'Week End...

ForAll可以实现许多操作,但开始构建公式时还需了解若干注意事项。 此公式可以包含执行操作的函数,比如使用Patch和Collect函数修改数据源的记录。 您无法修改作为 ForAll 函数对象的表。 其中包括对表使用Patch或Collect。 此公式可以调用连接方法。 您可以使用 ; 运算符对每条记录执行多项操作。
您可在 ForAll 中使用 Set 和 UpdateContext。 您可以使用 Collect 函数。 您可以使用 ForAllVariable 函数。 您可以使用 Patch 函数。 提交答案 下一单元: 总结 上一篇下一步 需要帮助? 请参阅我们的疑难解答指南或通过报告问题提供具体反馈。 反馈 此页面是否有帮助? 是否...

At first, you need to save the data for collection. Let’s take an example. Set the below formula on theOnStartproperty of your app: OnStart = ClearCollect(collectionname,SharePointlistname) Next, Use this collection to your specific requirement as like: ...
