Expression Validation

Expression Validation

You can validate an expression in a transformation while you are developing a mapping. If you do not correct the errors, error messages appear in the
Validation Log
view when you validate the mapping.
If you delete input ports used in an expression, the Developer tool marks the mapping as not valid.
