I have been working on an 'issue list' in which one user 'add an item' and assign responsibility to another user. I created a workflow in SPD 2013 and assign "Encoded Absolute URL" for an item. The purpose was the responsible user gets an email with the link to an issue and when he/she clicks on the link it will take the user to the SharePoint issue item.
The user is getting email but the link in an email is not working. When user click on the link, a file of size 0 KB is downloaded rather to take the user on the list item.
Use this instead:
Workflow Context -> Current Item URL
You can even use this in a hyperlink, using this as the address and the Title as the displayname of the hyperlink
Another option is to use the link with the current item id.
I use this often because I use different view's or if I want launch them right into edit mode
You may try this. Rather then using the absolute URL option, try using Add or Change lookup tab. The look should be like this : Data source: (Select your list here) Field from Source : (Select Title here)
Please let me know if it works.
