I am using Sharepoint On-Prem (the free version) and what I'm trying to achieve I thought would be simple. But I am very new to Sharepoint and coding so I am not sure how.
I have a custom list, that when an item is created it starts a workflow and assigns a to-do item to a user. That's working great.
So the user gets an e-mail follows the link to the to-do item, Clicks Edit ...
And here is my problem. I want the user to enter some information (Specifically select a date which is unlikely to be today's date) and click Complete. I want that information to be updated in the task (probably in the due date field). This will then get transferred back to my original list through a workflow.
So my question is this. Is it possible to edit the .aspx file through Sharepoint Designer to add an editable date field in the form, and update the task list? And if so, how do I do it?
Thanks
