Hi Samyukta,

I assume that you want to make a field mandatory and add options to it based on the selection of a variable on the service catalog. This can be done using -

1. First write a client script on the Service Catalog - Type-> OnLoad , Applies on Catalog Item View and Isolate Script Set to False

function onLoad() {
   this.form_g_form=g_form;
}

Then using this form_g_form object, write a client script inside multi-row variable set - 

 var main_form_variable_value=this.form_g_form.getValue("main_form_variable_name");
if(main_form_variable_value=="value"){
    g_form.addOption('var_1', 'choice_1', 'Choice1', 1);
    g_form.addOption('var_1', 'choice_2', 'Choice2', 2);
    g_form.setMandatory("var_1",true);
}

Please like and Mark as Correct if this solves your issue
