SharePoint List Field updates erroneously after item is created

[lth0ms0n]

Hi all, 

I have recently created a SharePoint list with a custom Power Apps form which one of my teams are using to track issues which are encountered in relation to the service we deliver to our customers. 

Using the "Created By" default field in the list, I have created a "Logged By" column, so we can see whom raised each issue, as they arise. 

My Power Apps form is configured to specify this as the Current User, so issues are automatically logged against the user who raised them - the field is also not changeable, so we always know whom raised each item on the list. 

It's only just gone live so, as you can imagine, teething problems and things not working as expected are starting to crop-up. One of the issues I've encountered is that, if I tweak one of the list items, this field is not only changing to my name but I can't replace the name of the user whom originally raised it. 

Here is how I see it working: 

1. The name of the analyst who is raising the issue is inserted into the field as they fill in the form 

2. This field cannot be changed by them so that each analyst is made responsible for the raising and tracking of their issues, through the form/list 

3. Whenever the form is opened, to examine more content of the list item (as not all fields are always visible) this field remains that analyst - so it's hard coded once the form is submitted as having been raised by that individual and not subject to change as it's modified (by myself, as needed) during the process. 

How do I code the field on the form so that the current user value is taken, the first time, and not each time the form is opened and saved? 

Thanks!

I'll assume you're using a Form Control. Change the Default property of the card based on whether the form is FormMode.New. Something like:

If(Parent.Mode = FormMode.New, User().Email, ThisItem.'Logged By')
