| Constraints by Family Feature (tigrt0135m000) |  |
| Use this session to link constraints to aspects of features. For each family aspect you can define a constraint. By using a constraint you can exclude values of the aspect that depend on the values of preceding aspects in the classification code. This procedure results in a family-dependent constraint, as the sequence of features in the classification code can differ by family. You cannot assign a constraint to the first aspect of a family, because in that case there is no predecessor aspect. Start the Constraints (tigrt0137m000) session from the Specific menu to display the constraints. Note If you have started this session by zooming, you can only find and select a record.

Fields | Description
Family | The family for which constraints are defined.
Family | The description or name of the code.
Feature | The feature of the family for which the constraint is defined. Note You must already have defined features in the Features (tigrt0101m000) session.
Feature | The number that refers to the aspect for which a constraint is defined.
Description | The description or name of the code.
Constraint ID | The code of the constraint is been defined for the aspect. Note You must already have defined constraint IDs in the Constraint ID (tigrt0136m000) session.
Description | The description or name of the code.
