# Removing mappings from an existing reference

Removing two mappings from the reference between the `TradeBase` and the `Delta` stores in the `Sensitivities` schema:

```Java theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
List<IPair<String, String>> referencesToRemove;
referencesToRemove.add(new Pair("RiskClass", "RiskClass"));
referencesToRemove.add(new Pair("RiskMeasure", "Measure"));
configurator.removeReferenceMappings("Sensitivities", "TradeBase", "Delta", referencesToRemove);
```
