SNOW-CAD Creating and customizing tables and data Practice Question
A developer is creating a new table 'u_incident_custom' to extend the Incident table. Which TWO configurations will ensure that the new table inherits the correct behavior and displays in the application navigator?
⚠ Common exam trap
ServiceNow often tests the distinction between table inheritance (Extends field) and navigator visibility (Display in application navigator), and candidates mistakenly think that setting a label or creating a module alone will achieve inheritance or navigator display.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set 'Application' to the desired scope and check 'Display in application navigator'
Setting 'Application' to the desired scope ensures the table belongs to the correct application context, and checking 'Display in application navigator' makes the table visible in the application navigator menu. Option D is correct because setting 'Extends' to 'Incident' establishes the inheritance relationship, allowing the new table to inherit all fields, business rules, and behaviors from the Incident table, which itself extends Task.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set 'Application' to the desired scope and check 'Display in application navigator'
Why this is correct
This ensures the table is scoped correctly and appears in the navigator.
- ✗
Create a module pointing to the new table
Why it's wrong here
Modules are for custom navigation; the table will appear automatically under its parent if configured.
- ✗
Set 'Label' to 'Incident Custom'
Why it's wrong here
Label is for display only and does not affect inheritance.
- ✓
Set 'Extends' to 'Incident'
Why this is correct
Extending the parent table ensures inheritance of fields, business rules, and ACLs.
- ✗
Set 'Extends' to 'Task'
Why it's wrong here
Extending Task would not inherit Incident-specific behavior like state model.
