required help @Vasantharajan N @Ankur Bawiskar @Voona Rohila @WillieW @RaghavSh 

As I need to automate the standard change request creation every 2nd Friday of the month for the change templates that I have with me along with that change tasks also need to create and those change tasks need to auto assign to assignment groups that I have with 

Short Description: [assignment_group] Microsoft Patching

Description: New Microsoft patches installed

Change Template:

1. Monthly Microsoft Patching

2. Monthly PMPC Patching

Assignment Groups:

1. Supply Chain Engineering
2. Corporate Engineering
3. Digital Engineering

make it run Daily and use the script I shared in condition and the other script field

Also I believe you should know how to use GlideRecord to insert new record into any table

If you are not aware then I will suggest to take scripting fundamentals course from now learning

But one thing is those Change Tasks need to auto assign to groups. So, that's the reason asking for script for creating change tasks and auto assigning them to groups.

Assignment Groups:

1. Supply Chain Engineering
2. Corporate Engineering
3. Digital Engineering

this is sample script

(function() {

    var templateName = 'your_standard_change_template'; // Replace with your template name

    var assignmentGroup = 'Microsoft Patching'; // Replace with your assignment group

    var change = new GlideRecord('change_request');

    change.initialize();

    change.type = 'standard'; // Ensure the change type is standard

    change.assignment_group.setDisplayValue(assignmentGroup);

    // Apply the template

    if (change.applyTemplate(templateName) == 0) {

        gs.info('Template applied successfully to change request');

    } else {

        gs.info('Failed to apply template');

    }

    // Insert the change request

    var changeSysId = change.insert();

    gs.info('Standard change request created: ' + changeSysId);

    // add logic here to create change tasks

    var rec = new GlideRecord('change_task');

    rec.initialize();

    rec.change_request = changeSysId;

    rec.short_description = 'Your Testing';

    rec.assignment_group.setDisplayValue('Supply Chain Engineering');

    rec.insert();

})();

I believe I gave enough script and solution which answers your question

with below script Change request and change task is getting created but the fields in the change request are not getting populated with the change template field values and it should execute on 2nd Thursday of every month so replaced with 4.

(function() {
    var templateName = 'sys ID of the Template'; // Replace with your template name
    
    var change = new GlideRecord('change_request');
    change.initialize();
    change.type = 'standard'; // Ensure the change type is standard

     // Apply the template
    if (change.applyTemplate(templateName) == 0) {
        gs.info('Template applied successfully to change request');
    } else {
        gs.info('Failed to apply template');
    }

    // Insert the change request
    var changeSysId = change.insert();
    gs.info('Standard change request created: ' + changeSysId);

    // logic to create change tasks
	
    var rec = new GlideRecord('change_task');
    rec.initialize();
    rec.change_request = changeSysId;
    rec.short_description = 'Your Testing';
	rec.description = 'Confirm business application functions as it should with new Microsoft patches installed.';
    rec.assignment_group.setDisplayValue('Supply Chain Engineering');
    rec.insert();

})();
