Mirror
The mirror attribute contains a copied value from another attribute value, depending on its configuration. Mirror attributes cannot be edited.
Mirror settings
You can use a mirror attribute to reflect the attribute value of another element. This element can exist in the same module, another module, or another workspace. You can mirror only one attribute.
Note To configure a mirror attribute, the module should have a minimum of one link attribute with Allowed Target Modules configured.If the link attribute targets more than one module and the linked-in element is from a module that does not contain the mirror attribute, the mirror attribute will be empty.
