Build Your Expression Set From a Template
To reuse or modify an expression set template’s components, save the template as an expression set or a version of an expression set. The template’s type determines whether you can save it as a new expression set or a version of an existing expression set.

Build Your Expression Set from a Read-Only Template
You can’t directly use a read-only expression set template because the template is inactive. To activate the template for reuse or to modify the template, save the template as an expression set.
-
From the App Launcher (
), find and select Business Rules Engine.
- From the app navigation menu, select Expression Set Templates.
-
Open the read-only expression set template that you want to use.
The names of read-only templates don’t have the Ready_to_Use prefix (1), and the templates don’t have the Executable checkbox selected (2).
-
Click Save As.
The Save As operation creates an expression set. The expression set’s first version is also created by default and opens in a new browser tab. The version inherits the template’s components, such as resources and steps.
To call the expression set from flows or use it as a subexpression, give the version a rank, and activate the version.
Build Your Expression Set or Version From an Executable Template
An executable template is active, so you can use it as-is in flows or as subexpressions. But you can’t make changes or additions to an executable template. To reuse a template’s components and then build on top of them, or to modify the components, save the template as an expression set or a version of an expression set.
-
From the App Launcher (
), find and select Business Rules Engine.
- From the app navigation menu, select Expression Set Templates.
-
Open the executable expression set template that you want to use.
Executable templates have the Ready_to_Use prefix (1) in their names, and have the Executable checkbox selected (2).
- Click Save As.
-
Select how you want to save the template.
Expression Set Saves the template as an expression set. Expression Set Version Saves the template as a version of the expression set that you select. -
Save your changes.
Depending upon your selection, a version of the newly created or the selected expression set opens in a new browser tab.
