Extract only updated rows

Question

Hi!
I've figured out how to get rows changed by update statement in replicat process (I don't need rows where column values stay unchanged).
Is it possible to filter these rows in extract process?

See Managing Conflicts in the Admin guide.
Edit:
You can also use GETUPDATEBEFORES
GETUPDATEBEFORES | IGNOREUPDATEBEFORES
Valid for Extract and Replicat
Use the GETUPDATEBEFORES and IGNOREUPDATEBEFORES parameters to control whether or not
the before images of updated columns are included in the records that are processed by
Oracle GoldenGate. Before images contain column details that existed before a record was
updated. Use the GETUPDATEBEFORES parameter in the Extract parameter file to extract
before images or in the Replicat parameter file to replicate before images.
You can compare before images with after images to identify the net results of a
transaction or perform other delta calculations. For example, if a BALANCE field is $100
before an update and $120 afterward, a comparison would show the difference of $20. You
can use the column-conversion functions of Oracle GoldenGate to perform the comparisons
and calculations.
You also can use GETUPDATEBEFORES to maintain a transaction-history table. For more
information about performing delta calculations and using transaction history, see the
Oracle GoldenGate Windows and UNIX Administrator’s Guide.
The GETUPDATEBEFORES and IGNOREUPDATEBEFORES parameters are table-specific. One
parameter remains in effect for all subsequent TABLE or MAP statements, until the other
parameter is encountered.
Default IGNOREUPDATEBEFORES
