Hello @Naman Jain2412 -

I have used Script Include + Onchange Client Script. Please use the script below -

Script Include -

// Name: DueDateCalculator
// Client Callable: True (important for GlideAjax)
// Description: Calculates a due date based on a given priority using GlideDateTime.

var DueDateCalculator = Class.create();
DueDateCalculator.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getCalculatedDueDate: function() {
        var priority = this.getParameter('sysparm_priority'); // Get the priority value from the client script
        var gdt = new GlideDateTime(); // Initialize GlideDateTime object with current time

        // Parse priority to an integer for comparison
        var parsedPriority = parseInt(priority);
        if (parsedPriority === 1) { // Critical: Add 60 days
            gdt.addDaysLocalTime(60);
        } else if (parsedPriority === 2) { // High: Add 90 days
            gdt.addDaysLocalTime(90);
        } else if (parsedPriority === 3) { // Moderate: Add 120 days
            gdt.addDaysLocalTime(120);
        } else if (parsedPriority === 4) { // Low: Add 180 days
            gdt.addDaysLocalTime(180);
        } else if (parsedPriority === 5) { // Planning: Add 10 days
            gdt.addDaysLocalTime(10);
        } else {
            return '';
        }
        // This format will typically match how ServiceNow displays date/time fields.
        return gdt.getDisplayValue();
    },

    type: 'DueDateCalculator' // Important: Must match the Script Include name
});

Client Script -

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        g_form.clearValue('due_date');
        return;
    }

    var ga = new GlideAjax('DueDateCalculator');
    ga.addParam('sysparm_name', 'getCalculatedDueDate');    // Specify the function within the Script Include to call
    ga.addParam('sysparm_priority', newValue);
	ga.getXML(getDueDateResponse);
    function getDueDateResponse(response) {
        var answer = response.responseXML.documentElement.getAttribute('answer');
        if (answer) {
            g_form.setValue('due_date', answer);
        } else {
            g_form.clearValue('due_date');
        }
    }
}

If my response was helpful, please mark it as correct and helpful.
Thank you.

@Naman Jain2412

on which table?

you can always use before insert/update business rule.

What should be set for Due date for different Priority?

Example: for P1 it should be 2 days from the time ticket was created etc?

sn_risk_mitigation_task

for P1 you can consider 2 days for p2 4 days p3 6 days p4 10 days p5 12 days.
if we use onchange client script then it is or business rule, based on this pls let me know the code

Ankur Bawiskar · ‎07-16-2025

@Naman Jain2412

you can use addDays() method in server side (business rule) and handle the logic.

what did you start with and where are you stuck?

Hi @Naman Jain2412 ,

My suggestion will be you please try code on your own and if you are facing some issue, then ask for help rather than asking for complete code.
