Consider your incoming message as follow, this will consider as the incoming body and will be accessed by $.{inbody} on the message body tab. This message body tabs have a payload.

<sales>
      <place>
      <name> Kerala</name>
      </place>
<date>2202102</date>
</sales>

Now to add additional details to the body header use ${header. give the proper message name} for sample code refer below image. Make sure you specify XPath in the Message header because here we are dealing with XML and if the element passing is the string you need to specify the data type as java.lang.string

${header. give the proper message name}
