Data Masker downloads schema information and saves it into your masking set. When the schema is changed, a manual refresh under Rule Controllers is needed, in order to configure rules against the new schema. However when the schema is modified dynamically by a Command rule or other rules, in order for subsequent rules to be aware of the modified schema, a dynamic refresh is necessary. This is what a group of refresh rules is designed for.

Specifically, Trigger Refresh rules will download the trigger data dynamically under the Rule Controller, so that subsequent rules will have access to these information. It also refreshes all the Trigger Disable/Enable rules under the same controller, in the same way that Refresh Triggers Form under Rule Controllers does. After the Trigger Refresh Rule is executed, all Trigger Disable/Enable Rules under the same controller will have the up-to-date view of the trigger information in the schema.
