TMC-20025: Ignored or Overridden Constraints


Violations of this rule identify constraints that are ignored due to having empty or invalid targets, or are overridden by other constraints. Targets can be empty or invalid if the constraint is out-of-order, where it is issued before a prerequisite constraint has been issued.


Review the list of ignored and overridden constraints, and either remove the constraints, edit them to become valid, or rearrange them such that the constraints are no longer out-of-order.

To check which constraint(s) override the target constraint, use "Report Exceptions..." under "Reports" for more details.
