To prevent customizations from being overwritten by system upgrades, the upgrade
process automatically skips changes to objects that have been customized. You may want to
overwrite your customizations when a software upgrade contains a feature that you would like
to implement.
Pourquoi et quand exécuter cette tâche
To identify customized objects, the system adds a
corresponding record in the Customer Updates [sys_update_xml] table. The table maintains
the current version information for all objects that have been customized. The upgrade
process skips changes to objects that have entries in the table. The upgrade process
does not skip objects if only excluded fields have changed.
