Sorry for the delay, i had to go get lunch - in any case, you would want to declare your variables (using the a!localVariables() parent) using the a!refreshVariable declaration and turn OFF "refresh on referenced variable change" for any local variables you'd like to remain static even when the original copy of the data is updated.

a!localVariables(
  
  local!originalCopy: a!refreshVariable(
    value: ri!myDataCDT,
    refreshOnReferencedVarChange: false()
  ),
  
  local!isDataUpdated: not(exact(
    tostring(ri!myDataCDT),
    tostring(local!originalCopy)
  )),
  
  a!formLayout(
    contents: { /* ... */ }
  )
)

Can you confirm whether you're working in an Appian version at or above 19.2?

I don't know of any way to "highlight" a field like this, but you could use a combination of side-by-side layouts and rich text fields with icons (as you seem to already suggest); you would want to store a copy of the original data in a local variable which does not change, and compare that to the value of the variable that DOES get updated, and you could set the visibility properties of the icon (appearance, color, size, captions, etc) depending on whether the data has changed or not.

since the oy way to highlight these input fields is to use the validations. please try the below approach if it's okay to use the validation highlight.

1. Save the initial value shown in the input components in a local variable(s) (say, local!original value) and make sure that all refresh is false.

2. Use a different local variable (say, local!current value) in the saveInto of these input fields

3. Compare the two local variables to through a validation if those are different.

4. Makesure that you use the validation groups to skip these validations during form submission

Note: The only drawback of this approach is that you may not be able to add any other proper validations to this field.
