Every workflow object, in addition to having a protection level, also records a customization level when you modify the object and save it to a database or file. An object's customization level helps control whether other users can modify the object based on their access levels, by allowing only users with an access level equal to or higher than the object's customization level to modify the object.
Note: The range of access levels allowed to modify the object may be further restricted by the object's protection level.
Setting the customization level ensures that a customizable object that has been customized never gets overwritten during a seed data upgrade, because the upgrade always occurs with the Workflow Definitions Loader operating at an access level below the customized object's customization level.
To set the customization level of an object, display the Access tab of the object's property page and either check or clear the Preserve Customizations check box. The customization level that you set for an object is dependent on the setting of the Preserve Customizations check box and on your current access level.
