Application IDs

Related applications should have the same application ID prefix. For example, all payroll applications could begin with P. If you use group definitions, you might consider using a unique prefix, like GRP, to identify all group definitions. The application ID field is 16 characters.

Avoid numbering application IDs. For example, HOUSEKEEP£1, HOUSEKEEP£2, and so on, because you might need a HOUSEKEEP£1.5.
