Update a materialization schedule for a data model element (Beta)

This endpoint updates the schedule of an existing materialization schedule for an element in a data model. Only the cron cadence and timezone are changed; the element must already have a materialization schedule. For more details on materialization, see [Materialization](https://help.sigmacomputing.com/docs/materialization). **Beta**: This documentation describes a public beta feature and is subject to the [Beta features](/docs/sigma-product-releases#beta-features) disclaimer. ### Usage notes - Retrieve the **dataModelId** by calling the [/v2/dataModels](https://help.sigmacomputing.com/reference/list-data-models) endpoint. - Retrieve the **elementId** by calling the [/v2/dataModels/{dataModelId}/elements](https://help.sigmacomputing.com/reference/list-data-model-elements) endpoint. - [Write access](https://help.sigmacomputing.com/docs/set-up-write-access) must be enabled on your connection. - To perform this operation, you must use API credentials owned by a user assigned to an account type with the **Schedule materializations** permission. - The element must already have a materialization schedule. To create one, use the [create data model materialization schedule](https://help.sigmacomputing.com/reference/create-data-model-materialization-schedule) endpoint.
