Sequences can be created to produce an incremental default value for attributes. To create a sequence:
You can modify a sequence by selecting it and clicking Modify.
You can delete a sequence by selecting it and clicking Delete. A message stating Are you sure you want to delete the sequence? is displayed. Click Yes to confirm the deletion.
Note:
You cannot delete a sequence if the sequence is referenced within a WorkView configuration. References must be removed before the sequence can be deleted.
