Summary

Important Observations

• Field validation rules are applied when table operations are performed. Because you have not yet created any tables, you cannot test the field validation rules in this exercise.
• There may be many ways of performing the same check.

Tips and Techniques

• Remember that most business rules should be defined for a table, not a field.
• If you use messages with the variables (e.g. &1), validation error handling will substitute the field label for this variable.

What I Should Know

• How to define rules for a field in the LANSA Repository.
• How to control the action performed when a rule is checked.
• How to define error messages for rules.
• How to adopt rules from a reference field.
