Need to receive lines via web service - Codeunit 74

We are trying to receive a purchase order via the web services. This thread looks like what we need:

https://community.dynamics.com/nav/f/microsoft-dynamics-nav-forum/281171/posting-invoice-to-purchase-order---through-web-service-code-unit/803158#803158

We are attempting to follow the steps, however when we use codeunit 74 as suggested, no valid WSDL is returned and therefore we cannot consume the service. Instead we receive this:

8306.Screenshot_5F00_3.png

That brings me to two questions:

Is this the correct methodology for this task? If not, what is?
If this is the correct method, why would we not get a valid WSDL and how can we consume it then?

Thanks!

The forum post you have referenced avoids use of direct codeunit usage as it’s not as good as using ODATA. Try this blog post out: https://demiliani.com/2019/06/12/dynamics-365-business-central-using-odata-v4-bound-actions/

in essence you want to put the onus on a codeunit being used via a page. The forum you referenced will become useful once you have a page you can feed some specific parameters to.
