Reorganize a Lifecycle Assembly

You can reorganize a lifecycle assembly under specific limitations.

Following limitations are:

New documents should not be added directly under the assembly root. They should always be added to leaf elements, which are children of folders.
Folders in the current sequence can be moved up or down.
An element cannot be demoted when the leaf directly above it is in a previous sequence.
When you drag an element to another element, it becomes the last child in the target element with the following exception: A leaf dragged to another leaf becomes the next sibling of the target leaf.
An element you promote becomes the next sibling of its previous parent.
An element you demote becomes the last child of its previous sibling.
To satisfy eCTD compliance, appended or modified leaf elements should not be placed under new leaf elements.
When an assembly is removed from the current active view, slip sheets that were added to the leaf and folder no longer appear in the assembly.
