# IMeasureDefinitionOverride

- Package: [@gooddata/sdk-model](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/index.md)
- Kind: interface
- Stability: alpha
- Source: https://github.com/gooddata/gooddata-ui-sdk/blob/rel/11.64/libs/sdk-model/src/execution/executionDefinition/index.ts

> **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md).
> 

(EXPERIMENTAL) Override for a catalog metric definition.
