# Reference

# Reference {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
A reference variable references a record in another table. For example, a variable named point_of_contact references the User \[sys_user\] table.
For attributes supported by this variable, see [variable attributes](https://www.servicenow.com/docs/ZgEltaCGp47m_kPHe5yO2w "There are a few Service Catalog variables support specific attributes to define the behavior and restrictions for variables.").  
Keep the following information in mind when you create a reference variable:

* Reference variables use the [auto-complete feature](https://www.servicenow.com/docs/access?context=c_AutoCompleteForReferenceFields&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US) . To ensure that users have enough information to make the selection, configure the [reference lookup list](https://www.servicenow.com/docs/access?context=c_ReferenceLookup&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US) .
* Reference variables store the sys_id of the selected record (like reference fields). To use the display value in a script, use the same methods as for a reference field.
