hello All ,

how to override warehouse_tree.js in my custom app .
I want to override onrender function in frappe.treeview_settings in my custome app to be like this …

if(frappe.user.has_role("System Manager")) {
                    if (node.data && node.data.balance!==undefined) {
                        $('<span class="balance-area pull-right">'
                        + format_currency((node.data.balance), node.data.company_currency)
                        + '</span>').insertBefore(node.$ul);
                    }
            }

instead of :

                    if (node.data && node.data.balance!==undefined) {
                        $('<span class="balance-area pull-right">'
                        + format_currency((node.data.balance), node.data.company_currency)
                        + '</span>').insertBefore(node.$ul);
                    }
