Payload for service FollowUpDocumentNotification

Hi all,

our purpose is to update opportunity with follow up document number created in ERP

For this purpose we execute the web service FollowUpDocumentNotification with following Payload.

In web service message monitor Incoming webservice status is Successful but nothing change in opportunity document.

Could someone send us a working paylod for service FollowUpDocumentNotification?

Where can we find documentation that explain how the payload must be compiled?

Payload:

<ns0:FollowUpDocumentNotification xmlns:ns0="http://sap.com/xi/SAPGlobal20/Global">
