Hi @abhisek ,
Hope you are doing well.
Proposed Solution
In order to achieve this task, you have 2 suitable options to get the solution of the query and I personally tried it on my Personal Developer Instance to get the solution as soon as possible:-
1. Create "onChange-Catalog Client Script" on the Date Field and "Script Include" and make a "GlideAjax" call with this. For reference, check below scripts:-
Script Include:-
var RestrictSelectionofPastDate = Class.create();
RestrictSelectionofPastDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {
restrictPastDate: function() {
var date = this.getParameter('sysparm_date');
var curDate = gs.now();
if (date < curDate) {
return false;
} else {
return true;
}
},
type: 'RestrictSelectionofPastDate'
});Client Script:-
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
//Type appropriate comment here, and begin script below
var ga = new GlideAjax('global.RestrictSelectionofPastDate');
ga.addParam('sysparm_name', 'restrictPastDate');
ga.addParam('sysparm_date', g_form.getValue('select_date'));
ga.getXML(getValidation);
}
function getValidation(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
if (answer == 'false') {
alert("You can't select the Past Date. Kindly choose the date of today or after it.");
g_form.setValue('select_date', ''); // Empty the variable.
}
}2. Create "Catalog UI Policy" and add the Filter Condition and write script like down below.
For your reference, also attaching screenshots of the outputs that will give you better insights of how the scripts are working or the best thing will be to follow the solution and execute the scripts on your instance.
If you find this information/knowledge/solution helpful, Please don't forget to mark my solution and reply as helpful and accepted.
