Every item in Production Reporting has a security mode that is on or off.
The security mode for all items derived from a secure Production Reporting file is on. These items include the Production Reporting document, all output files, the Production Reporting ProgramOutput item, and the SPFFileOutputCollection item. If a file is secure, this information is displayed in Properties (on the Advanced tab).
It is possible to create a secure Production Reporting program that produces secure and nonsecure output. The Production Reporting program can be coded so that some pages are output without security, while the rest are secure. In this case, users with access to the output files through normal EPM Workspace access control see the nonsecure output pages and the secure pages that they are authorized to see. The ability to create secure and nonsecure pages within a secure Production Reporting program is governed with the security command in Production Reporting.
You can create on replace a version of a secure report, but the security mode for the new version and the original must match.
