Access: Cascading combo and list boxes with LinkMasterFields/LinkChildFields

What changed

LinkMasterFields and LinkChildFields can now link combo or list controls so a parent selection filters the child control without custom VBA code.

Why it matters

The no-code cascading-control behavior can replace VBA logic, but existing Access forms and filtering edge cases must remain compatible.

Known limitations

• Availability, prerequisites and rollout scope remain authoritative in the linked Microsoft documentation.

Now check

• Confirm the supported Access build and rollout channel
• Test LinkMasterFields and LinkChildFields in a copy of a production database
• Validate filtering, null values and compatibility with existing VBA
