i want to update an existing watchlist to include a new user for all new incidents.

[Wayne DeCoste]

Hello.

We have a new user on the support team. How do I update an existing watchlist with this new user so he is notified when a new incident is created, or an existing incident is updated/closed? 

Is there a way to do this without running a script? 

Thanks!

FYI - I tried running my query through GPT and it suggested:

var gr = new GlideRecord('incident');
gr.addQuery('active', true); // filter as needed
gr.query();
while (gr.next()) {
// Append without overwriting
var currentWatch = gr.watch_list ? gr.watch_list.split(',') : [];
var newUser = '6816f79cc0a8016401c5a33be04be441'; // sys_id of user
if (currentWatch.indexOf(newUser) === -1) {
currentWatch.push(newUser);
gr.watch_list = currentWatch.join(',');
gr.update();
}
}

But, not being a java guy, Im not sure of this accomplished what I am trying to do ...

And, I dont want to overwrite the existing watchlist, just append.

@Wayne DeCoste ,

Use this script, It will update the watchlist if the user is not present in there.

var userToAdd = 'a8f98bb0eb32010045e1a5115206fe3a'; // sys_id of the user

var gr = new GlideRecord('incident');
gr.addQuery('active', true);
gr.query();

while (gr.next()) {
    var currentWatchlist = gr.getValue('watch_list') || '';  
    var watchlistArray = currentWatchlist.split(',').filter(Boolean); 

    if (watchlistArray.indexOf(userToAdd) == -1) {  
        watchlistArray.push(userToAdd);
        gr.setValue('watch_list', watchlistArray.join(','));
        gr.update();
        gs.print(gr.number + " updated watchlist: " + gr.watch_list);
    } else {
        gs.print(gr.number + " already had the user in watchlist");
    }
}

Good morning! And thank you. 
So, this script will update any existing incidents, and add the user to any new incidents that are created?
