Hi team,

Many of us either don’t know about or don’t bother configuring the cascade delete rule when creating or configuring a reference field on a table. The cascade delete rule is very important if you want to perform some action on a record when its referenced record is deleted from the system.

You can configure what should happen to records that reference another record when that referenced record is deleted.

Steps to configure:

  1. Navigate to the reference field on the table.

  2. Right-click and open Configure Dictionary.

  3. In the Reference Specification section, you can choose an option from the Reference cascade rule.

If you select Delete, it will also delete the record that is referencing the record that was deleted.
Selecting Restrict will prevent the referenced record from being deleted.

For more information, please check the product documentation for cascade delete rules.

Thank you.
