Modifying Masks 

Product masks allow you to partition a single master repository into as many customized, virtual subset repositories as you like.

The main uses of masks are to edit an arbitrary subset of records as a group, and to publish custom “subset catalogs.”

For more information about masks, see Product Masks.

The Masks table must already have been created for the repository (using the MDM Console), and the individual mask(s) already defined before you can add records to, remove records from, or replace records in a mask.

To add a new mask or delete an existing mask from the hierarchy of masks, you can use the Modify Mask command described in the next section, or you can go into Hierarchy mode and edit the Masks table directly.
