SNOW-CAD Working with Data Practice Question
An admin created a new table 'u_custom_asset' with a reference field to 'cmdb_ci'. After creating a form, users report that when they select a CI, additional fields do not auto-populate as expected. What is the most likely cause?
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
✓
The reference field lacks a reference qualifier or default value configuration for auto-population.
Reference fields on custom tables do not auto-populate other fields unless configured with a reference qualifier or default value. ACLs (B) would block read access, not auto-population. A business rule (C) is not necessary for basic auto-population. The cmdb_ci table (D) can be referenced from custom tables.
