Following are descriptions of the steps for purging projects in Oracle Projects.
Create a purge batch, or modify an existing purge batch. A purge batch is a list of projects whose data you want to purge and/or archive.
See: Create a Purge Batch.
To modify an existing purge batch, see Modifying a Purge Batch.
Review and revise the list of projects in the batch. See: Review and Refine the List.
Run the ADM: Validate Purge Batch process to determine whether the projects in the purge batch are eligible for purging. See: Validate the Projects in the Purge Batch.
Release the batch for purging. (You cannot release a batch that contains errors.) See: Release the Purge Batch.
Finally, run the purge process (ADM: Purge Project Data), which purges batches that have passed the validation process. See: Start the Purge Process.
