在项目中，我们需要写一个自定义的Web Dynpro应用程序，以方便用户的业务流程。此业务流程的活动大多是有关批准，与不同层次的审批者。每个审批人（批准/拒绝）后，通过电子邮件发送到相关人士。完全不同的电子邮件将被发送超过10次。我们必须要找到一个有效的方式来发送电子邮件。
即使有10个以上不同内容的电子邮件，或多或少的它们具有相同的结构。例如“信尾”大多都会这样“这是一个计算机自动生成的信息。请不要回复。” 这意味着，如果我们找到一个有效的方式进行分组，电子邮件和编写代码，维护更容易对我们来说，不管用户将来需求如何变化。这时我想到使用Smartforms。 Smartforms的控制流和条件以及文本元素(text element)，将帮助我实现想法。我只需要创建一个Smartform，使用电子邮件模板传递我的信息.
一般情况下，该方案像这样，通过代码调用Smartforms- >传递参数（如我想用哪个模板） - >收到的内容，用它做什么- >发送邮件。
首先，通过Smartforms创建电子邮件模板，架构架构，创建新的文件夹，新的条件。
在条件选项卡中，我们可以决定哪些内容显示：
我们甚至可以使用HTML标记来写HTML邮件的内容，例如<BR/>线，<A>标签的URL
然后，我们需要激活Smartform在WebDynpro侧。设定援助类的方法，调用Smartform。传递参数的模板，把有必要的内容写入邮件.
后调用的Smartforms的，它会返回一个结构，保持内容的类型SSFCRESCL一个OTF领域中。
在调试模式下，我们注意到，OTF数据是可读的，内容的电子邮件和一些奇怪的数字。
我们需要发送HTML格式的电子邮件，使用方法cl_document_bcs=> create_document。 i_text参数是一个表型SOLI_TAB的，底层的数据结构是一个字符。我们现在的任务是从OTF转换到SOLI，同时仍然保持正确的内容. 首先，我们将转换为OTF表TLINE.

看更具有可读性，不是吗？现在，所有我们需要做的是将其转换为SOLI删除一些多余的线条。

完美！现在，我们可以使用这些内容发送电子邮件了
