I have created a new workflow in SharePoint designer 2013 in which when a date has been reached then the users needs to be informed that one section if missing needs to be completed. But I want to know that how can I do it automated because there are 3 options with the checkbox which says in short:
- When an item is created
- Manual start
How can I do this is SharePoint Designer 2013 so that it knows when a date has been approached and will inform the user about it. Without any change in the list.
