Hello Narayanan,

Use calculated values to achieve this. Below is sample example.

dojo.provide("com.example.calculatedvalues");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");
(function() {
    dojo.declare("com.example.calculatedvalues", null, {
        getValue: function(attribute, workItem, configuration) {
                       var url = "String to add to other attribute (Filed)";
                       return (url);
        }
    });
})();

Once the script is done, Goto Types and Attributes.
-> Select a work item type which work items require this script.
-> Select an attribute where you want change and add calculated script.
