Adding the variable editor to custom tables that are NOT task based

Out of the box, only tables extended from task can make use of the variable editor. To extend this functionality to custom non-task based tables, you need to take the following steps.

Create a Variable Editor

1. Navigate to System UI > Formatters

2. Click Create New

3. Fill at the form as below and submit

   • Name: Variable Editor

   • Formatter: com_glideapp_questionset_default_question_editor

   • Table: Select your custom table

   • Active: true

   • Type: Formatter

Finally, navigate back to the form for your custom table, and add your new Variable Editor to it by personalizing the layout.

Ensure new Variable Editor is reportable and editable

Once created, the new editor is not really actionable. It’s view only. There is a simple fix, though, as described in KB0538897.*

1. Navigate to System Definition > Tables

2. Select your table

3. Create a new column on the table as follows:

   • Type: Variables

   • Column Label: variables

   • Column name: variables (this must be exact, you cannot have a u_ in the column name value)

   • Active: true

4. Navigate to the form view of your table, personalize it, and removed the new Variables field

* ServiceNow Support recommends that this be completed by them by putting in a Support Case. The Variables type is not a visible Field class for selection when creating a field. While you can make the field class visible, I would recommend you request this from ServiceNow Support.
