Use Mule Data Mapper to enrich an existing payload

i have a Mule flow that gathers calculations information from an external service to enrich a list of Invoices. So, I end up (after the enricher scope) with my calc info in a flow variable, and my original invoices in the payload.

Can I use the data mapper to inject my calculation values into the existing invoice objects?

Currently I'm using a Groovy script - but prefer config over scripting.

You can use the datamapper transformer within an enricher scope to enrich parts of the payload.

The enricher can enrich the payload if you set the 'target' to a named field on a POJO for example, or if your payload is a Map, the enricher will add a new entry to the Map.

<enricher>
   <datamapper... />
   <enrich target="#[payload.field1]" source="#[payload.datamapperoutputfield1]" />
   <enrich target="#[payload.field2]" source="#[payload.datamapperoutputfield1]" />
</enricher>
