Add responsible employee in web service ManageSupplierInvoiceIn

Hi everyone

Currently we are defining a web service request structure for creating a supplier invoice.

An invoice is created successfully (status: Exception) but the following error message is coming up:

"Party of role responsible employee missing"

In the web service documentation there is no description how to add a responsible employee.

We also tried to reuse the section which is coming back in the response from a Read-operation of a supplier invoice that has a responsible employee assigned (manually). By reusing this section in the request to create a supplier invoice no responsible employee was added.

To sum it up my question is: How to add a responsible employee by creating a supplier invoice via web service?

Thanks + Best Regards,

Daniel
