When you  select  Planned Start Date on  change form, validate if Planned Start Date is after 10 days of current date. If not display an error message below the field and clear the value selected.

You need to have client script for that to validate instantly.

If you want to go with server script then error message is not shown until you click on save/submit button. 

It is easier with UI policy and also better option than server side because it will throw the error message instantly to user when he give the date.

Mark as correct and helpful if it solved your query.

Server side aswell you can do that without even script.

Create a Before Insert Business rule on change request table as below

Condition :

And in Actions Tab, you can set as below

Hi Nikita,

Here is the script - 

Onchange client script

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var ga = new GlideAjax('uDateUtils');
ga.addParam('sysparm_name', 'getTenDays');
ga.getXML(alertAnswer);

function alertAnswer(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");

//var end_date=g_form.getValue('start_date');
//var dif=answer-end_date;

var d1=getDateFromFormat( g_form.getValue('start_date'), g_user_date_format);
diff=answer-d1;
if (diff < 1) {
g_form.setValue('start_date', '');
g_form.showErrorBox('start_date', "New start date should be after 10 days from today",'error');
}
}
//Type appropriate comment here, and begin script below

}

Script Include

var uDateUtils = Class.create();
uDateUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getTenDays: function() {
var gdt = new GlideDateTime();
var today = gdt.getLocalDate();
var fdt = new GlideDateTime(today);
fdt.addDays(10);
return fdt.getNumericValue();

},
type: 'uDateUtils'
});

Hi there,

Have you considered using a (Catalog) UI Policy to achieve date validations? There's almost no-code needed to achieve date validations this way. Have a look at an article I wrote on this:
No Code date validations thru (Catalog) UI Policies

If my answer helped you in any way, please then mark it as helpful.

Kind regards,

Hi,

you can use UI policy for this requirement as below.

create UI policy and when to apply select your date field and use condition as below as before 10 days from now.

On script tab: check select run scripts true and on execute if true use below script.

alert("Enter valid date, You cannot select date before 10 days from now");
    g_form.clearValue('yourdatefield');

Thanks,

Pavankumar
