PeopleSoft encrypts the access ID when it is stored in the PeopleTools
security tables. Consequently, an encrypted value can’t be
readily referenced or accessed. So when the access ID, which
is stored in PSACCESSPRFL, must be retrieved or referenced,
the query selects the appropriate access ID by using the
symbolic ID as a search key.
The symbolic ID acts as an intermediary entity between the
user ID and the access ID. All the user IDs are associated
with a symbolic ID, which in turn is associated with an
access ID.
If you change the access ID, you need to update only the
reference of the access ID to the symbolic ID in the
PSACCESSPRFL table. You do not need to update every user
profile in the PSOPRDEFN table.
