Runtime Constant in XSLT :-(

Question

Hi together,
I have one problem with constant at the runtime.
The tag <RCVPRN> is empty, but I need this for my IDoc communication.
In the SAP help stands this:
Runtime Constants
$ReceiverService
Service on the receiver side that receives the message. For example, the name of a business system.
As of SAP XI 3.0, use this constant instead of the constant RECEIVER_SYSTEM used previously.
Yes

If you want to access one of the constants in the XSLT program, you first have to declare the constant as a parameter, for example:
<xsl:param name="MessageId" />
In my XSLT mapping I have this:
<RCVPOR>empty</RCVPOR>
<RCVPRT>LS</RCVPRT>
<xsl:param name="ReceiverService"/>
<RCVPRN>
<xsl:value-of select="$ReceiverService"/>
</RCVPRN>
</EDI_DC40>
But during the runtime the constant is empty
  <RCVPOR>empty</RCVPOR>
  <RCVPRT>LS</RCVPRT>
  <RCVPRN />
   </EDI_DC40>
Have you an idea for my problem?
Bye
Stefan

Hi Udo/all,
Thank you for your answer.
Please see in my last post:
Idoc with XSLT Mapping ALE service error
I mark in my channel:
Take Sender from Payload and Take Receiver from Payload
I must set control field by xslt maping, because the receiver is flexible.
With your setting I became a converting error to an ALE logical system.
I need the runtime constant in the xslt mapping.
Idea?
bye
