Recommendations for ensuring the security of secure Production Reporting jobs and documents in EPM Workspace:
Establish dedicated user accounts for secure Production Reporting or SPF jobs.
Use a dedicated account for one secure report or a group of related secure reports.
Ensure that secure jobs are run only from dedicated accounts.
Limit access to the dedicated account to as few people as possible, because everyone with access to it can import secure jobs and access the Production Reporting document, which contains all data.
