Hi Attanhes

Backing out an update set creates delete updates in the current update set. If you commit, back out, and then reapply a remote update set, errors appear in the previewer because the deleted updates are considered more recent changes and cause collisions.

Do not back out the Default update set. This action can damage the configuration of the instance.
The back out process reverses both record-level updates and changes to the dictionary. Some changes caused by a back-out can result in data loss. These are the expected results of the back-out process:-
 
Note: If you commit, back out, and then reapply a remote update set, errors appear in the previewer because backing out an update set creates delete updates in the current update set. The deletes are considered more recent changes and cause collisions.

Batch update sets enable you to group update sets together so you can preview and commit them in bulk.

Dealing with multiple update sets can lead to problems, including committing update sets in the wrong order or inadvertently leaving out one or more sets. You can avoid these problems by grouping completed update sets into a batch.

The system organizes update set batches into a hierarchy. One update set can act as the parent for multiple child update sets. A given set can be both a child and parent, enabling multiple-level hierarchies. One update set at the top level of the hierarchy acts as the base update set.

When you preview or commit the base update set, you preview or commit the entire batch. The system determines the processing order, and checks for collisions, based on the dates the changes were recorded, and on their sequential ancestry. Their ancestries are the specific instances in which the changes in the update sets took place.
