Creating a table lookup for a study allows the system to check for a sequential customized subject ID to give to each subject that is added to the system. For example, a study may require that when a subject is added but fails certain criteria, they get a different formatted ID than the ones that are successfully enrolled and taking part in the study. At the same time, they need to be sequential regardless of the format. A common application of this scenario is with screening IDs versus subject study IDs, where every subject gets a screening ID of <SITEID-00X>, where X is a sequence, but subjects who are successful get a slightly different format of <SITEID-40500X>. The system is able to keep the total population sequential regardless of which of those formatted IDs is assigned.
Example 1:
Subject 1 is successful and gets 301-205001
...
Subject 4 is successful and gets 301-205004
Example 2:
Subject 1 is successful and gets 301-001-4001
