When you add or edit a DQM rule, you should validate it before applying the DQM rule to source data.
The validate function is used to validate all rules, in relation to each other, for a whole segment. Validation that can be performed on a single rule is automatically performed when you save the rule.
When you log into the configuration console, an automatic validation check is performed to see if the DQM rules are valid. If an error is found, a header message will display at the top of the configuration console screen. Click the Review the errors link to open a new window describing the errors.
