setDisplayValue not working for scoped app

[Munna1]

HI Everyone,

I am trying to use setDisplayValue within workflow run script activity.

When I do so, I get the following error.
Error: Function setDisplayValue is not allowed in scope xyz__.

Is there any workaround for this?

Run Script code : 

var too = current.variables.to_stockroom;
var fl = current.variables.from_stockroom;
var toloc = current.variables.to_stockroom.location.name;
var frloc = current.variables.from_stockroom.location.name;
var frStockName = current.variables.from_stockroom.getDisplayValue();

var to = new GlideRecord('alm_transfer_order');
to.initialize();
to.setDisplayValue('from_stockroom', fl); //current.variables.<name of variable>
to.setDisplayValue('to_stockroom', too);
to.setDisplayValue('from_location', frloc);
to.setDisplayValue('to_location', toloc);
to.insert(); //creating transfer order record based on the variables
var parentID = to.number;
var attachID = "";

var sctask = new GlideRecord('sc_task');
sctask.addQuery('request_item', current.sys_id);
sctask.query();
if (sctask.next()) {
    var gr = new GlideRecord('sys_attachment');
    gr.addQuery('table_sys_id', sctask.sys_id); //Get excel sheet attachment sys_id
    gr.orderByDesc('sys_created_on');
    gr.setLimit(1);
    gr.query();
    if (gr.next()) {
        attachID = gr.sys_id;
    }
}

var row = '';
var inputStream = new GlideSysAttachment().getContentStream(attachID); //Passing the attachement sys_id

var parser = new sn_impex.GlideExcelParser();
parser.parse(inputStream);

var headers = parser.getColumnHeaders();
var header1 = headers[0];

while (parser.next()) {
    row = parser.getRow();
    if (row[header1] != null) {
        var aset = new GlideRecord('alm_hardware'); //Querying assets in hardware table
        aset.addEncodedQuery('stockroom!=NULL^serial_number=' + row[header1]);
        aset.query();
        if (aset.next()) {
            if ((aset.stockroom != fl) || (aset.substatus == 'pending_transfer') || (aset.substatus == 'Law hold') ||(aset.install_status != '6')) {
                if (aset.stockroom != fl) {
                    current.work_notes = 'Invalid Insert: ' + row[header1] + ' does not belong to the Stockroom: ' + frStockName;
                } else if (aset.substatus == 'pending_transfer') {
                    current.work_notes = 'Invalid Insert ' + row[header1] + ' asset already on an active transfer order line ';
                }
                else if (aset.substatus == 'Law hold') {
                    current.work_notes = 'Invalid Insert ' + row[header1] + ' asset is under Law Hold, cannot create transfer order line ';
                } else if (aset.install_status != '6') {
                    current.work_notes = "Invalid Insert: " + row[header1] + " asset is not in 'In Stock' State";
                }
            } else {
                var alm = new GlideRecord('alm_transfer_order_line'); //If the conditions matches above criteria create a new order
                alm.initialize();
                alm.setDisplayValue('request_line', current.getUniqueValue());
                alm.setDisplayValue('transfer_order', parentID);
                alm.setDisplayValue('model', aset.model);
                alm.setDisplayValue('asset', aset.display_name);
                alm.setDisplayValue('quantity_requested', 1);
                alm.insert();
                var childID = alm.number;

                var m2m = new GlideRecord('u_m2m_tasks_assets');
                m2m.initialize();
                m2m.u_asset = aset.sys_id;
                m2m.u_task = current.getUniqueValue();
                m2m.insert();
            }

        }
    }

Hi,

That seems to indicate the values are being set. Now, the problem is with something different.

Can it be the Transfer Order Line is in Reserved status?
