Summary

REP003 - Validation Rules

Important Observations

• Field validation rules are applied when file operations are performed. Because you have not yet created any files, 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 file, not a field.

• If you use messages with the variables (e.g. &1), validation error handling will substitute the field label for this variable.
