I already shared solution for your same question in another thread.
sharing here again
you can use after insert business rule on sys_attachment
Condition: current.table_name == 'sc_task'
Script:
(function executeRule(current, previous /*null when async*/ ) {
// Add your code here
var gr = new GlideRecord("sc_task");
gr.addQuery("sys_id", current.table_sys_id);
gr.addQuery("request_item.cat_item.name", "ServiceNow Suppor");
gr.query();
if (gr.next()) {
new GlideSysAttachment().copy("sc_task", gr, 'sc_req_item', gr.request_item.sys_id);
}
})(current, previous);
If my response helped please mark it correct and close the thread so that it benefits future readers.
