task brazil Updated Sep 10, 2026 1 min read edit-function-field.md

The user who created a function field or a user with the admin or function_field_admin role can edit the definition of a saved function field. It isn’t possible to edit the label or the return type of a saved function field.

Before you begin

Role required: admin, function_field_admin

Procedure

Navigate to Platform Analytics Administration > Core UI artifacts > Reports.
Select a report based on the table that you want to edit a function field on.

When you configure a function field, it is available in any report or data visualization on the same table. For example, a function field that calculates how long incidents have been open is available for all reports and visualizations on the incident table.
Open the Configure tab and select Configure function field.
Enter text in the Search functions box to find the function field you want to edit.

Search functionality searches on the Label of the field, the name of the field, and the function definition.
Select a new operation, new fields the function operates on, or both.

Validation of the edited function may indicate that it returns an invalid result.
Select Save.

If one or more reports use the function field, you see a link to a list of those reports. You can review the list, select Save anyway, or select Cancel.

Result

The results of the edited function field replace the old results in all reports in which the function field is used.
