Dependency Conflicts
If you attempt to delete an item (such as a rule variable, staff account, or queue) referenced in a rule, the system checks to see if the item is related to business rules. If it is related, then a dependency conflict might occur.
You will not receive a dependency conflict warning if you delete a product, category, or disposition used in a rule. However, if you try to delete a custom field that is used in incident rules, you will see a Dependency Conflict window that describes the conflicts.
Before you can delete the custom field, you must resolve the dependency by editing or deleting the rule that causes the dependency.
Note: If you delete an email or survey that is used in a Send action in a contact,
incident, or opportunity rule, you can still activate the rule base but the rules engine
will not process the action. No error will be logged to indicate that the mailing or survey
was not sent. The system doesn't perform a dependency check if you use enhanced business
rules.
