The Read-Only attribute specifies whether an object or an object property is editable. Certain objects and object properties in Metrics Management are non-editable. For example, the period type object and the list of excepted locations that appears in Setup Measures—Locations are both non-editable. Metrics Management assigns the Read‑Only attribute to non-editable objects and properties in the XML export file. The following example shows the Read-Only attribute for the Parent Measure property of a measure in an export file:

The Read-Only attribute equals True for non-editable XML elements. If you change the Read-Only attribute for a non-editable object to False and import, the import fails.
