Trying to generate multiple picking tickets combined into a single pdf via a suitelet. Not able to get it to work. Unexpected error (the best kind)

var tranId = [5599467, 5599591];

                var xmlStr = '<?xml version="1.0"?><!DOCTYPE pdf PUBLIC "-//big.faceless.org//report" "report-1.1.dtd">'
                xmlStr += '<pdfset>';


                for (var i = 0; i < tranId.length; i++) {

                    var salesOrderRec = record.load({

                        type: record.Type.SALES_ORDER,

                        id: tranId[i]

                    });

                    var renderer = render.create();

                    renderer.setTemplateByScriptId('CUSTTMPL_SSA_V1');

                    renderer.addRecord({

                        templateName: 'record',

                        record: salesOrderRec

                    });
                    log.debug("Renderer: "+ renderer);
                    // Escape ampersand in logo url

                    // xmlStr += renderer.renderAsString().replace(/&(?!(#\\d+|\\w+);)/g, "&$1");

                }

                xmlStr += '</pdfset>';

                var pdfFile = render.xmlToPdf({

                    xmlString: xmlStr

                });

                context.response.writeFile({

                    file: pdfFile

                });

As far as I remember you need to generate the individual PDFs, save them to the file cabinet, make them available without login to be able to merge them using pdfset.

you can also do pdf elements like the attempt here

Interesting, that’s a picking ticket template

an actual template will start wtih

<?xml version="1.0"?><!DOCTYPE pdf PUBLIC "-//big.faceless.org//report" "report-1.1.dtd">

which is not a pdf element

https://bfo.com/products/report/docs/tags/tags/pdfset.html @alien4u is describing this line, using the file url. This is what I've done, but it does need to be available without login:

<pdf src="resource/coverpdf.pdf" />
