1st you need to know which API that OOTB script include is using

did you check that?

generateDocument method within script include GenerateBiaPdfUtil?

@Ankur Bawiskar Below is the generateDocument method

 generateDocument: function(biaName, docTemplateName) {
        var templateId;
        var docCategory;
        var templateGr = this._getDocTemplate(
            this.documentTemplateTable,
            docTemplateName
        );
        if (templateGr && templateGr.isValid()) {
            templateId = templateGr.getValue('sys_id');
            docCategory = templateGr.getDisplayValue('category');
        }

        var docName = docCategory ? docCategory + '-' + biaName : biaName;
        var docNameWithExt = docName + this.FILE_EXTENSION;
        this.deleteExistingDocument(docNameWithExt);

        var attachmentId = new sn_doc.GenerateDocumentAPI().generateDocumentForTask(
            this.biaSysId,
            templateId,
            docName
        );
        var pdfDownloadLink = attachmentId ?
            this._getPdfDownloadLink(attachmentId, biaName) :
            null;

        return {
            attachmentId: attachmentId,
            downloadLink: pdfDownloadLink ? pdfDownloadLink : biaName,
        };
    },

And this method "generateDocumentForTask" is below

	initiateDocumentTasks: function(taskGr, htmlBody, docTemplateId, generatedPdfName, documentId) {
		var flowInputs = {};
		flowInputs['task_record'] = taskGr;
		flowInputs['template_id'] = docTemplateId;
		flowInputs['generated_pdf_name'] = generatedPdfName;
		flowInputs['document_id'] = documentId;
		if (!gs.nil(htmlBody) && taskGr.document_template.sys_class_name.toString() == "sn_doc_html_template")
			flowInputs['html_body'] = htmlBody;
		var result = sn_fd.Subflow.startAsync('sn_doc.automatic_document_task_creation', flowInputs);
		if (gs.nil(result) || gs.nil(result.contextId)) {
			gs.error('Automatic Document Task Creation flow failed to start. Template ID: ' + docTemplateId +',Task ID: '+ taskGr.getValue('sys_id'));
			return false;
		}
		var gr = new GlideRecord('sn_doc_task_execution');
		gr.initialize();
		gr.setValue('task',taskGr.sys_id);
		gr.setValue('document_template',docTemplateId);
		gr.setValue('flow_context',result.contextId);
		gr.setValue('status','initiated');
		gr.insert();
		return true;
	},

	isDocumentTasksExecutionActive: function(taskGr, docTemplateId) {
		var gr = new GlideRecord('sn_doc_task_execution');
		gr.addQuery('task',taskGr.sys_id);
		gr.addQuery('document_template',docTemplateId);
		gr.addQuery('status','!=','closed');
		gr.query();
		return gr.hasNext();
	},

    generateDocumentForTask: function(recordId, documentTemplateId, pdfName) {
        var isValid = this._validateUserAccess(documentTemplateId, recordId);
        if (!isValid) { 
            gs.error("User do not access to the record");
            return null;
        }

        var documentTemplateGr = this._getGlideRecord("sn_doc_template", documentTemplateId)();
        var templateType = new DocumentTemplateUtils().getTemplateType(documentTemplateGr);

        if (templateType == "sn_doc_pdf_template")
            return new PdfTemplateUtils().generate(recordId, documentTemplateId, pdfName);
        else if (templateType == "sn_doc_html_template")
            return new HtmlTemplateUtils().generate(recordId, documentTemplateId, pdfName);
    },

            "message": "Error while generating pre-filled document"
        };			
        var isValid = this._validateUserAccess(documentTemplateId, recordId);
        if (!isValid) { 
            response.message = "Data is incorrect or User does not have access to the record";
            return response;

        }

        return false;

@sunil maddheshi 

it looks like it's using OOTB GenerateDocumentAPI

see if that supports page number

if not then have your PDF Generation logic

Hi @sunil maddheshi 

Read this Article for adding page number : Document Template: Dynamic Header and Footers

Also you can check :Generating Custom PDFs - using the new PDFGenerationAPI

@Tanushree Maiti The article you shared uses PDFGenerationAPI, while BCM code uses GenerateDocumentAPI. Those are different APIs.
