Issue with usage of ServiceOrderQuotationCRMChangeRequestConfirmation

Hi guys,

my aim is to use the standard enterprise service ServiceOrderQuotationCRMChangeRequestConfirmation to update the Service Order Quote. Unfortunately, when I use the request below, the service says the execution was successful, but the BP doesn't change.

Do you have experience with thsi service? Can you please give me some hints how to change the request so the BP get changed?
