Expression Validation

Expression Validation

You can validate an expression in a transformation while you are developing a mapping. If you did not correct the errors, the Designer writes the error messages in the Output window when you save or validate the mapping.
If you delete input ports used in an expression, the Designer marks the mapping as invalid.
