Dynamic label on catalog form

[saisahithiA]

I have written onchange client script where I am setting the label of a variable on runtime. based on the other variable selection . But in RITM it is still showing old label name. Please advise on this .
NOTE:

• RITM displays variable names and labels based on the variable definition in the catalog item, not the dynamic label applied during form rendering.
• g_form.setLabelOf() updates the UI only for the current session; it does not persist the label to the variable’s value or metadata.
  
  My Script:
  
  function onChange(control, oldValue, newValue, isLoading) {

      if (isLoading || newValue == '') return;

  
  

      var sourceValue = g_form.getValue('source_field');

      var labelText = '';

  
  

      if (sourceValue == 'AAA') {

          labelText = 'XXX';

      } else if (sourceValue == 'BBB') {

          labelText = 'YYY';

      } else {

          labelText = 'ZZZ';

      }

  
  

      // ✅ Smooth label update

      setTimeout(function() {

          g_form.setLabelOf('source_data', labelText);

      }, 300);

  
  

  }
  O/p:
  on RITM it is still showing label name "source_data"

Hi, you should set the field "Applies on Requested Items" on your Catalog Client Script to true.

2 things to perform and then verify

1) ensure your catalog client script runs on RITM as well. Mark "Applies on Requested Item" as True

2) also update your script as this -> remove isLoading check so that your onchange runs when form loads as well

function onChange(control, oldValue, newValue, isLoading) {

    var sourceValue = g_form.getValue('source_field');
    var labelText = '';

    if (sourceValue == 'AAA') {
        labelText = 'XXX';
    } else if (sourceValue == 'BBB') {
        labelText = 'YYY';
    } else {
        labelText = 'ZZZ';
    }

    // :white_heavy_check_mark: Smooth label update
    setTimeout(function() {
        g_form.setLabelOf('source_data', labelText);
    }, 300);


}
