If the status is Initial, you can change layout details.
Active
A layout with status Active cannot be changed.
To make changes, copy the current layout to a new version
number.
To use the layout with the new version number:
Set the status of the active layout to Expired.
Set the status of the layout with the new version number to Active.
Note
Alternatively, you can set the status of the layout with the
new version number to Active at once. The status of the previous version will
then be set to Expired automatically.
