Optimizer's inability to resolve variables for partitioning - response (3) by SANJI

Thanks for the response Dieter.
I tried creating the view, but that doesn't seem to change the plan.
CREATE VIEW SSURI.V_CDC1 (BATCH_START, BATCH_END)
AS
SELECT     CAST(BATCH_START AS TIMESTAMP(6)),
        CAST(BATCH_END AS TIMESTAMP(6))
FROM    SSURI.CDC_BATCH1;
EXPLAIN SELECT * FROM SSURI.CUSLDSFL_SI
WHERE AUD_TIME >= (SELECT BATCH_START FROM SSURI.V_CDC1)
AND      AUD_TIME <= (SELECT BATCH_END   FROM SSURI.V_CDC1)

 4) We do an all-AMPs RETRIEVE step from SSURI.CDC_BATCH1 by way of an
     all-rows scan with no residual conditions into Spool 1 (all_amps),
     which is built locally on the AMPs.  The size of Spool 1 is
     estimated with high confidence to be 1 row (35 bytes).  The
     estimated time for this step is 0.03 seconds.
  5) We do an all-AMPs DISPATCHER RETRIEVE step from Spool 1 (Last Use)
     by way of an all-rows scan and send the rows back to the
     Dispatcher.
  6) We do an all-AMPs RETRIEVE step from SSURI.CDC_BATCH1 by way of an
     all-rows scan with no residual conditions into Spool 2 (all_amps),
     which is built locally on the AMPs.  The size of Spool 2 is
     estimated with high confidence to be 1 row (35 bytes).  The
     estimated time for this step is 0.03 seconds.
  7) We do an all-AMPs DISPATCHER RETRIEVE step from Spool 2 (Last Use)
     by way of an all-rows scan and send the rows back to the
     Dispatcher.
  8) We do an all-AMPs RETRIEVE step from SSURI.CUSLDSFL_SI by way of
     an all-rows scan with a condition of (
     "(SSURI.CUSLDSFL_SI.Aud_Time <= :%SSQ18) AND
     (SSURI.CUSLDSFL_SI.Aud_Time >= :%SSQ17)") into Spool 3
     (group_amps), which is built locally on the AMPs.  The size of
     Spool 3 is estimated with no confidence to be 122,089,337 rows (
     117,572,031,531 bytes).  The estimated time for this step is 2
     minutes and 54 seconds.
