Symptom
In the Data Maps, it is not possible to overwrite standard mappings via Map Function / Cross Reference / Custom Script
Environment
Boomi
Reproducing the Issue
In Boomi, go to Atom Management -> Environment Extensions -> Data Maps and select the Data Map with the standard Mapping. The overwritten value isn't considered.
Cause
Boomi allows the existing standard mappings to be overwritten but with an exception. Only those standard mappings can be overwritten that are a direct source-destination mapping, i.e. the destination should not be mapped via a Map Function / Cross Reference / Custom Script
Resolution
This is the expected behaviour in Boomi.
