Sequence Recon Field on the resource object form

Sequence Recon If you select this check box, then reconciliation events are processed
in the sequence in which they are created.
The application of this feature can be illustrated by the following
example:
Suppose there are two reconciliation events for the OIM User
resource object for user John Doe. The first reconciliation event (E1)
data is as follows:
■ Login: testuser1
■ First Name: John
■ Last Name: Doe
■ Organization: Xellerate Users
■ Type: End-User
■ Role: Full-Time
The second reconciliation event (E2) data is as follows:
■ Login: testuser1
■ First Name: John1
■ Last Name: Doe1
■ Organization: Xellerate Users
■ Type: End-User
■ Role: Full-Time
Between the first and second events, the first name and last name of
the user was changed.
During trusted source reconciliation, if events are processed in the
order in which they are created, then this change in first and last
names is correctly reconciled into Oracle Identity Manager. However,
if the second event is processed before the first one, then data in the
target system does not match data in Oracle Identity Manager at the
end of the reconciliation run. This inconsistency will be reflected in
the auditing tables, and will remain until another event from the
trusted source is created for this user.
If you enable the Sequence Recon option, then you can ensure that
events for the same entity (for example, same user or same process
form) are processed in the order in which they were created.
