Defining Header Mappings
You use a header mapping to map the values of the following key fields in the receiver agreement to other values:
● Sender party
● Sender communication component
● Receiver party
● Receiver communication component
The address fields (sender, receiver) are then transformed correspondingly in the header of the outbound message.
The header mapping is particularly important when configuring business-to-business processes in which the business partners want to replace the names of their internal business systems with neutral representatives (party, business component).
More information: Configuring Business-to-Business Processes
You can do the following in the header mapping:
● Specify fixed values
● Define that the conversion of the field values is to be determined dynamically from the message payload

Header mappings are only supported by the following receiver adapters:
XI adapter
IDoc-Adapter
HTTP adapter
RNIF Adapter 2.0
RNIF Adapter 1.1
CIDX-Adapter
To specify the header mapping for an address field, perform the following steps:
...
1. Select the relevant field under Header Mapping (for example, Sender Communication Component).
2. Enter the target value for the key field.
If you want to specify a fixed target value for
parties or communication components, select the relevant party or
communication component using input help (
).
If you want to define that parties or communication components be determined dynamically from the message payload, proceed as follows:
a.
Select
the arrow beside the input help icon (
).
b. Choose Advanced.
The party editor or expression editor for communication components is opened.
c. To determine the party or the communication component dynamically, select the Dynamic radio button and enter a context object or an XPath expression.

3. Choose Apply.
If you want to replace the internal name of a sender business system in the outbound message with a neutral name of a party and communication component, specify the fields for Sender Party and Sender Communication Component in the header mapping.
