Attachment as URL in Billing Document : API_CV_ATTACHMENT_SRV/CreateUrlAsAttachment

Dear SAP Community, We are implementing the SAP API_CV_ATTACHMENT_SRV service in ADT for S/4HANA Public Cloud. We’ve created a Service Consumption Model based on a downloaded EDMX file. However, some operations like AttachmentContentSet(Post) and CreateUrlAsAttachment(Post) are not supported by the classes generated by the Service Consumption Model.
