SharePoint 2013工作流将日期设置为null或为空或空白 [英] SharePoint 2013 Workflow set date to null or empty or blank

问题描述

我需要使用 SharePoint 2013工作流来清除/设置为空/删除日期字段中的日期.我尝试将其设置为1/1/0001，创建一个空变量并将其设置为该变量，然后添加一个隐藏的日期列 那是空的，并将其设置为该值，似乎没有任何效果.我知道这可以在SharePoint 2010工作流程中使用，但是 在SharePoint 2013工作流程中执行此操作至关重要.另外，我不想创建SharePoint 2010工作流，然后再从SharePoint 2013工作流中调用它.这似乎应该是一件容易的事，但是我已经搜索了 在线，找不到解决方案.

谢谢

I need to use a SharePoint 2013 workflow to clear/set to null/delete the date in a date field.  I've tried setting it to 1/1/0001, creating an variable that's empty and setting the value to that, and adding a hidden date column that's empty and setting it to that value and nothing seems to work.  I know this will work using a SharePoint 2010 workflow but it's critical that we do this in a SharePoint 2013 workflow.  Also, I don't want to create a SharePoint 2010 workflow and then call it from my SharePoint 2013 workflow.  This seems like it should be an easy thing to do, but I've searched online and can't find a solution. 

Thank you,

Anthony
