For users of classic GIFTS and GIFTS Alta, there exists a Purge utility which lives in the GIFTS directory as gfwPurge.exe. This utility has the ability to assist users in purging a series of Request records in bulk from your database.
To use the utility, please follow the attached documentation, which provides detailed steps on how the Purge utility functions. Please bear in mind that, if the database is not backed up before the purge takes place and you wish to restore records, you will be unable to do so as the Purge utility will have removed these records from the database entirely. It is highly recommended to backup the database before running the Purge tool.
