# Configure field write options

# Configure field write options {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Within the Mobile SDK, when writing data to a ServiceNow instance through a REST endpoint, you can define field write
options.
You configure field write options using the [FieldWriteOptions class - iOS](https://servicenow-prod.fluidtopics.net/GX2mI1Cv8Rqz1fThp2c9Wg#FieldWriteOptionsiOSStruct "The FieldWriteOptions class provides functions that set the options for updating or creating fields in a record on a ServiceNow instance.") structure. This structure enables you to configure:

* Whether to suppress automatic generation of system fields.
* Whether to set field values using their [display value](https://www.servicenow.com/docs/access?context=c_DisplayValues&version=australia&pubname=australia-platform-administration&ft:locale=en-US)[display value](https://www.servicenow.com/docs/access?context=c_DisplayValues&version=australia&pubname=australia-platform-administration&ft:locale=en-US) rather than their actual value.
