Using a mandatory repository

A mandatory repository identifies resources that have templates or views that will be used to anonymize or scramble the data.

If a repository is defined as mandatory for the current user, access to the resources that are defined in the repository as mandatory is limited to the following interfaces:

The edit and view functions in File Manager Base component and FM/Db2
The browse and edit functions in FM/IMS

Access to the resources can only be through the template or view that is defined in the repository.

Dynamic scrambling

If the corresponding template or view contains scrambling definitions, then the data will be scrambled before it is displayed. Unselected field values will be initialized to zero or blank depending on the field type. For edit or view sessions these fields are protected, and insert, repeat, and delete commands are unavailable. Only formatted views of the data are available. This provides the capability to scramble or hide sensitive information for certain user groups when the data is accessed using File Manager.

The TESTMASK command can be issued on the View or Edit entry panel. This command toggles the scrambling option, which will force the usage of the template and restrict the function to view or browse dialogs.

Note: To enable dynamic scrambling through the TESTMASK command the resource entry must be marked as mandatory.
