Select this option to have all existing list items updated once the Workplace ID is added to the list. If this option is not enabled, the list item’s workplace ID will not be updated until the item is edited. When the Workplace ID is added to a list, it uses the internal SharePoint ID to create the sequence of ID’s.
Default: True
TIP: You can change the Workplace ID syntax at any time. To do this, delete the Workplace ID field and then add it back into the list or library with the new syntax. The IDs are regenerated when you click OK. When Lookups are created, they do not look up to the Workplace ID field itself; this is prevented. Instead, create a calculated field that uses the value in the Workplace ID. Thus, if you change the Workplace ID syntax or the syntax of the calculated field, the Lookups within a site will remain intact and the change will cascade down to the related fields in child lists.
