You can purge the data of your organization. When you purge data, you permanently delete data from the data store without deleting data models and other configuration details.
You can purge data in the development, QA, and production environments. You can choose to purge all business entity records, source records, and relationships, along with historical data. You can also choose to purge all historical data from business entity records, hierarchies, and relationships or purge records that belong to a specific business entity.
Only one tenant can run one purge job at a time per POD. When a purge job is in progress and you run a purge job, the job is queued.
You can purge a maximum of 1 million master records at a time. If you have more than 1 million master records, you have to run the purge job multiple times. For information about viewing the number of master records in your organization, see Monitor MDM SaaS.
Guidelines for purging data
Before purging data, consider the following guidelines to prevent any data issues:
•No users have logged in to the business applications.
•No jobs are running.
•All workflow tasks are complete.
•Don't update the metadata of any business entity while the purge job is running.
•Don't train any machine learning models.
