To configure a prefix value, you need the Manage System Settings feature privilege. If you don't have the Manage System Settings privilege enabled, you can view the prefixes, but you can't edit them.
Configuring the prefix for auto-generated reference IDs does not impact IDs that you manually assigned.
You cannot edit or update a manually-assigned reference ID in the auto-generated format of <prefix>-<reference ID number>.
1In Metadata Command Center, go to the Configure page.
2Click the Reference IDs tab.
3Select an asset type from the list.
4In Edit Reference ID window, modify the prefix value.
5Click Save.
