    • Revert a customization, back out the update set rather than deleting it.

    Administrators can delete an update set only when it isn’t the current update set and contains no sys_update_xml entries. For example, after merging update sets, you might want to remove the original sets. This capability is governed by an access control rule (ACL) applied to the sys_update_set table.

    Don’t delete sys_update_xml entries, because this action:
    • Doesn’t undo the updates.
    • Removes any record of who applied the customizations.
    • Removes the sys_update_xml entries associated with the update set, so customizations are overwritten when the instance is upgraded.

    When you try to delete an update entry, a warning message appears. Select OK to confirm the deletion.
