You can modify existing regions using the Modify Region page.
The Modify Region page also enables you to disable a region from further use. Entities that currently use the region will be unaffected, but the region will not be available as a selection for new or existing entities going forward.
Note: If the region's definition language differs from your session language, you cannot modify the region. Click Why? in the header and see the Multilingual User Interface Guide for more information.
To modify existing regions:
Log on to PPM.
From the menu bar, select Open > Administration > Regions > Browse Regions.
The Manage Regions page opens.
Click on the desired Region Name.
The Edit Region page opens.
Make the desired changes.
