There are 8 options available to select from when using DIU to perform an import from a third party data source.
Delete Existing Personnel Record if Duplicate Card Found - if a card/credential is being imported and there's an existing one in Symphony AC, the DIU will delete the existing duplicate card/cred
Card Number is in Hexadecimal - will convert the card number being imported to a hexadecimal value in Personne Manager
Index based on Personnel Field - this is used to select a unique identifier from an Symphony AC Personnel data field if you elect to import only the changes/updates from the same data source. This will prevent the import of duplicate personnel records
Download Personnel Record During Import
Full - Select this to perform a full Personnel download AFTER the import is completed. This is the recommended option
Single - Select this to perform a single credential download, one at a time, after the import is completed.
Hide Message Boxes - Select this to hide ALL message boxes that the DIU displays, such as successfuly import and errors during imports. This is useful when you do not want to acknowledge every message box during the import of thousands of records
Do Not Update Access Levels for Existing Records - Select this if you are assigning Access Levels to each cardholder during the import but do want to alter the Access Levels of the existing cardholder
Do Not Add New Records - Select this option is you do not want to import new records, but only want to import changes to existing records. This works in conjunction with Option 3.
Active Directory: Do Not Import sub-OU - Select this option if your data source is Acitve Directory (requires separate license) and you do not want to import AD accounts stored in nested OU (Organizational Units)
