A user with the admin role can delete a function field from its table. Deleting a function field is useful if you want to create a function field with the same name as one that exists on that
table.

## Before you begin

Role required: admin

Function fields are stored as columns on the table that you create them on. To delete a function field, you delete the associated column.  
Important:  
\>No check is made on a where a function field is used when you delete. In addition, deleting a function field is not reversible.

## Procedure

1. Navigate to AllSystem DefinitionTables.
2. Select the table with the function field that you want to delete.
3. Select the column to open its form.
4. Select Delete Column.  
   You can only delete the column if the Column name begins with <kbd class="ph userinput">u_</kbd> or <kbd class="ph userinput">x_</kbd>. If the Column name begins with something else, it was created by ServiceNow support. Contact support to delete it.

## Result

The function field is deleted and can no longer be used in data visualizations.
