InfoPath Dev

Hi I have a list with InfoPath form as attached Picture 1. Before, the column "Title" is with a link to the display view of form and open menu by default. After I added a rule setting the value of the "Title" in my InfoPath form (I deleted the rule afterwards), the Column "Title" value becomes blank in the SharePoint list and I can't go to the display view by clicking it or find the open menu. I wonder if I can attach a link to the display view of the form and the open menu to the Column "Request No."? If not, can I get them back on Column "Title"? Thanks!

If you modify the view you can add the "Edit" column which will display an icon you can click to edit the item. But you might just want set the "Title" field to your "Request No" value and then rename the Title field in the list. That would probably be easiest. In terms of the data already in the list, you can put the list in quick edit or spreadsheet view (what it is called depends on your SharePoint version) and just copy the request number data over.
