How to copy attachment from email using inbound action

[Blair5]

I have an inbound action that creates a service request. Currently, I have it set to attach the email to the RITM and I also want to include whatever attachments were on the email. See below for the script -- I see that it should happen by default, but that's not the case. What's missing?

createRequest();

function createRequest(){
	var cart = new Cart();  //calling the cart API
	var gu = gs.getProperty('standards.generic_user'); // sys id generic user
	var ds = gs.getProperty('standards.item');
	var item = cart.addItem(ds);  //sys_id of the catalog item I want to fire

	cart.setVariable(item, 'subject', email.subject); //sets catalog variable to the email's subject
	cart.setVariable(item, 'emailbody', email.body_text);  //sets catalog variable to email's body

	var usr = new GlideRecord('sys_user');
	usr.addQuery('email', email.from);
	usr.query();

	if(usr.next()){
		//if user is found in user table, set the requested for and opened by to that user
		cart.setVariable(item, 'requested_for', usr.sys_id);
	}else{
		cart.setVariable(item, 'requested_for', gu); //generic user
	}

	var rc = cart.placeOrder();  //this launches the catalog item, and creates a request object.  rc = the request object
	updateRITM(rc.sys_id);  //call a function immediately to update the ritm.  This must be a nested function, otherwise inbound actions get weird.
	//also, we're passing the sys_id of the request so we know what RITM to grab.
}

function updateRITM(req){
	var strEmailContent = email.content_type + "\n" + email.headers + "\n\n\n\n" + email.body_text;
	var sa = new GlideSysAttachment();

	var ritm = new GlideRecord('sc_req_item');
	ritm.addQuery('request', req);  //req is what we passed from the previous function. the sys_id of the request.
	ritm.query();
	while (ritm.next()){
		ritm.setValue('requested_for', email.from);
		ritm.contact_type="email";
		sa.write(ritm, email.subject + ".eml", " application/octet-stream ", strEmailContent);

		if (sys_email.hasAttachments()){
			gs.log('has attachments');
			var att = new GlideRecord("sys_attachment");
			att.addEncodedQuery("table_name=sc_req_item^table_sys_id=" + sys_email.getValue("sys_id"));
			att.query();
			while (att.next()){
				att.table_name = "sc_req_item";
				att.table_sys_id = ritm.getValue("sys_id");
				att.update();
			}
		}
		ritm.update();
	}
}

Hi Brian, can you help me out with my script, it is just only generating the sa.write function and copying the actual attachment itself. Here is the whole script 

createRequest();

function createRequest() {

    current.comments = "received from: " + email.origemail + "\n\n" + email.body_text;
    current.short_description = email.subject;

    var cart = new Cart();

    var item = cart.addItem('d912ff6d87f5b110daf7fc08cebb3567');

    cart.setVariable(item, 'subject', email.subject);  

    cart.setVariable(item, 'emailbody', email.body_html);

    var rc = cart.placeOrder();

    updateRITM(rc.sys_id);
}

function updateRITM(req) {
    var strEmailContent = email.content_type + '\n' + email.headers + '\n\n\n\n' + email.body_text;
    var sa = new GlideSysAttachment();

    var ritm = new GlideRecord('sc_req_item');
    ritm.addQuery('request', req);

    ritm.query();

    while (ritm.next()) {

        ritm.contact_type = "email";
        ritm.requested_for = gs.getUserID();
        ritm.description = email.body_text;
        ritm.short_description = email.subject;
        sa.write(ritm, email.subject, strEmailContent);
        GlideSysAttachment.copy('sys_email', sys_email.sys_id, 'sc_req_item', ritm.sys_id);


        if (sys_email.hasAttachments()) {
            var att = new GlideRecord('sys_attachment');
            att.query();

            while (att.next()) {
                att.table_name = 'sc_req_item';
                att.update();
                sys_email.target_table = 'sc_req_item';
                sys_email.instance = ritm.sys_id;
            }
        }

        ritm.update();

    }
}

createRequest();
