when incident is resolved attachment need to delete. disable attachment onload.

Hello @keerthana 

Greetings!

I think it's not best practice to delete the existing attachments. For future reference, its better to keep the  attachments 

refer the below thread to disable attachment.

please mark the answer as correct and helpful if helped!

Kind Regards,

Create BR

(function executeRule(current, previous /*null when async*/) {
if (current.state === 6 /* Resolved */) {
var attachments = new GlideSysAttachment().getAttachments(current.getTableName(), current.sys_id);
for (var i = 0; i < attachments.size(); i++) {
var attachment = attachments.get(i);
new GlideSysAttachment().deleteAttachment(attachment.getValue("sys_id"));
}
}
})(current, previous);

Hi there,

Can you explain the why of your requirement? Never heart of such a requirement, sounds strange to do this for all incidents, though maybe you have a solid case for this. Do share so we understand your situation better and can help you correctly instead of just sharing a piece of code.

Hello @keerthana 

Write this onLoad() Client Script :-

function onLoad(){

var state = g_form.getValue('state');
if(state == 'resolved'){
g_form.setReadOnly('u_attachment', true);
}

}

Plz Mark my Solution as Accept and Give me thumbs up, if you find it helpful.
