IDOC Headerfield Mapping

Hi,

I'm trying to setup a szenario 3rd Party(HTTP) -> XI -> R/3(IDOC).

In the R/3 I need the headerfields (EDI_DC40) SNDSRT="KU" and SNDPRN="M0001" for the right partnerprofile. I mapped the headerfield in the IB Directory (communication channel and receiver agreement).

The mapping seems to works fine, but from the adapter I got the error message: "Unable to convert sender XI party http://sap.com/xi/XI/XIParty to an IDoc party".

What is the reason for this error?
