I have a file whose header and body are both important to me and i need to mix some fields from the header and body to produce an outgoing message.
Eg:
AA,BB; [HEADER]
[BODY]
a,b,c,d,e,f,g,h…
a,b,c,d,e,f,g,h…
a,b,c,d,e,f,g,h…
a,b,c,d,e,f,g,h…
a,b,c,d,e,f,g,h…I want to extract fields AA,BB and a,b,c in the same orchestration.
I have promoted these header fields and have context message properties.
Now I need to get the value of these properties to assign them to outgoing messages.
I read a few acticles on promotion but I need examples and not just overviews.

There are a number of ways of doing this.
1. Declare the properties you wish to use on the outbound message, using the same properties schema used for the header.
In a message assignment you can copy the message context:
outputmessage(*) = inputmessage(*); //copies all properties
outputmessage(Your.property) = inputmessage(Your.property)
The output pipeline will demote the properties into the appropraite message fields.1. You can specifically assign values to the outputmessage using distinguished fields or the xpath function
outputmessage.field = inputmessage(Your.property);
xpath(outputmessage,<xpath of field>) = inputmessage(Your.property)
