How to add/leverage label of a property in the config parameter key of web portal?

Hi Team,

I would like to place a condition in the 'label' of property of config parameter key "VI_ObjectView_Person_Fields" in order to display a custom value. For example if the value of any property is empty for the searched user in the Person table , I want to display the value as  'No' for that column/property in User's profile

I tried using the collection SourceObject , however I am unable to refer any property. For example, if IsNullOrEmpty(from SourceObject select current customproperty01) then translate ('#LDS#No').It is throwing error as  " The property SourceObject.CustomProperty01 could not be found"

Can you please help me fix this?

Best  regards,

Prakash
