XMLCdata function usage issue in Business Centra

KumarManish

Hello Friends,
Would like your suggestion on the below issue about a web service.
I was upgrading my NAV 2016 CAL code to AL for Web service Integration which include Cdata section.
In Nav 2016 , I achieved Cdata with AppendChild and CreateCdataSection function but in AL I can't see such
functions.

I have created successfully created XML file in AL from the following reference.
https://community.dynamics.com/nav/b/diveshboramsdnavblog/archive/2018/03/05/vs-code-xml-dom-management-part-1

community.dynamics.com/.../creating-soap-request-message-in-al

But I am stuck in inserting Cdata section.
I also tried XMLCdata Functions available in Business Central but error occured -->
The requested operation cannot be performed in this context.
I am trying to generate below XML File with Cdata Section in Business Central.

<soapenv:Envelope xmlns:ord="https://moultonordervision.com/Ws/OrderStatusWebService.asmx&quot; xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"&gt;
<soapenv:Header />
<soapenv:Body>
<ord:OrderStatus>
<ord:strXml><![CDATA[<dataQuery><username>XXX</username><password>XXXXX</password><group_code>TEST</group_code><order_no>03027515</order_no></dataQuery>]]></ord:strXml>
</ord:OrderStatus>
</soapenv:Body>
</soapenv:Envelope>


I tried XMLCdata datatype given in AL but not succeeded in XML fiel creation with Cdata Tag.
