When you create a data profile, a data quality file (.dq) is created. A second file - the data quality Runtime Configuration File (RTC) file - is also created (.dq.rtc). The files share the same name but have different file extensions. For example, if the data profile file name is test.dq, then the RTC file is test.dq.rtc. The RTC file opens in the Profile Editor.

The data quality file (.dq) contains data profile information, including data quality rules, data quality schema, dimension configurations, and lookup keys (if lookups are used). The data quality RTC file (.dq.rtc) contains data profile runtime information including macros, logging information, SMTP server details, source dataset configurations, configurations of the four targets (Pass, Fail, Drilldown, and Statistics), and any lookups referenced in the data profile

You can save additional data quality RTC (.dq.rtc) files for a JSON data profile to perform additional development or testing without changing the existing data profile (.dq) file or the RTC (.dq.rtc) file. If you are developing in a development or test environment and eventually want to move the data profile to a production environment, then you can use one RTC file for the development environment and the other RTC file for the production environment (a concept similar to macros).

To create another RTC file for the same data profile:

If you click on the .dq file to open it in the editor (example, Test.dq), this opens the default RTC file (Test.dq.rtc). If you want to open the data profile using a different RTC file other than the default, double-click on the required RTC file.
