To avoid mapping of other fields in payload, you can try this -

<pre><code>%dw 1.0
%output application/json
---
(payload - 'details') ++ (payload.details - 'dcsId')
</code></pre>

It first gets everything in payload excepts details then add details by excluding dcsId.

This is my JSON request and I want to remove <code>dcsId</code> field from my JSON payload in DataWeave transformation.

How can I do that?
