Hi,
I want to Auto Populate the Due Date (17/07/2025 10:38:09) based on Priority as (1.Critical, 2.High, 3. Moderate, 4.Low, 5.Planning). Pls let me know the relevant code for this as per the requirement.

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.

var gdt = new GlideDateTime();

var priority = parseInt(newValue);

// Define the due date based on priority

if (priority == 1) { // Critical

// Example: 4 hours from now

gdt.addDaysLocalTime(60);

} else if (priority == 2) { // High

// Example: 1 day from now

gdt.addDaysLocalTime(90);

} else if (priority == 3) { // Moderate

gdt.addDaysLocalTime(120);

} else if (priority == 4) { // Low

gdt.addDaysLocalTime(180);

} else if (priority == 5) { // Planning

gdt.addDaysLocalTime(10);

} else if (priority == '') {

// Optional: Clear or set a default if priority is not matched

// (priority == 'None')

g_form.clearValue('due_date');

return;

}

// Set the due_date field

// g_form.due_date = gdt.getDisplayValue();

g_form.setValue('due_date', gdt.getDisplayValue());

Hello @Naman Jain2412 ,

Debug the code. Put it alert inside the if statement and see if it is going to the if statement.

@Naman Jain2412 - Why can't you use a combination of Script Include and onchange client script? Is there any reason?
