Hi Allen,

If you are looking for mandatory attachments on any catalog item. uou need to create catalog client script.

Using below script, you can achieve this.

function onSubmit() {

var cat_id = gel('sysparm_item_guid').value;

var gr = new GlideRecord("sys_attachment");

gr.addQuery("table_name", "sc_cart_item");

gr.addQuery("table_sys_id", cat_id);

gr.query();

if (!gr.next()) {

alert("You must attach a file to submit.");

return false;

}

}

Please mark helpful/correct answer if it is applicable.

Thanks,
