Hi @pavankumars3585 , For users to allow selected date after 3 days. You can use UI policy to achieve this.

Create an onChange client script and write this script - 

var dateStr = g_form.getValue('date_field_name'); // replace field name

if (!dateStr)
return;

var selectedDate = new Date(dateStr);
var today = new Date();

selectedDate.setHours(0, 0, 0, 0);
today.setHours(0, 0, 0, 0); // sets time to midnight

var allowedDate = new Date(today);
allowedDate.setDate(today.getDate() + 3);

if (selectedDate.getTime() !== allowedDate.getTime()) {

g_form.addErrorMessage('You must select a date exactly 3 days from today.');
g_form.clearValue('date_field_name'); // replace field name
}

This will also clear the value if wrong value is added so from won't be submitted before entering the valid date.

hi @pavankumars3585 ,

Create one onchange catalog client script, and select your date variable and use the below code .

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    var selectedDateStr = g_form.getValue('your_date_variable_name'); // Replace with your variable name
    var selectedDate = new Date(selectedDateStr);
    selectedDate.setHours(0, 0, 0, 0);

    // Get Today
    var today = new Date();
    today.setHours(0, 0, 0, 0);

    // Get Target (Today + 3)
    var targetDate = new Date(today);
    targetDate.setDate(today.getDate() + 3);

    // Check if the selected date is Today OR within the next 3 days
    // Logic: selectedDate >= today AND selectedDate <= targetDate
    if (selectedDate.getTime() < today.getTime() || selectedDate.getTime() > targetDate.getTime()) {
        g_form.clearValue('your_date_variable_name');
        g_form.showFieldMsg('your_date_variable_name', 'Please select a date between Today and 3 days from now.', 'error');
    } else {
        g_form.hideFieldMsg('your_date_variable_name');
    }
}

Hi there @pavankumars3585 

Try with a onlnoad script 

function onLoad() {
    var d = new Date();
    d.setHours(0,0,0,0);
    d.setDate(d.getDate() + 3);

    var yyyy = d.getFullYear();
    var mm = ('0' + (d.getMonth() + 1)).slice(-2);
    var dd = ('0' + d.getDate()).slice(-2);

    g_form.setValue('delivery_date', yyyy + '-' + mm + '-' + dd);
}

Use a UI policy for this - quite simple and no need for scripting
