Dynamic Search-help in Selection Screen Parameter

Question

Hi,
Please can you provide some solution for the below requirements.
I have 2 fields ( Organization channel and Team ) in my selection screen. Under one organization channel there can be many teams.
And I am trying a  dynamic search help on both the fields using event AT selection-screen on Value request and
FM 'F4IF_INT_TABLE_VALUE_REQUEST'.
But I am facing the below issue .
First I am giving some values in field 'Organization channel' . Then I am clicking on F4 button on my  2nd field 'Team' .
and in debugging mode under the event  'At selection-screen on value request', Select option SO_Team is blank.
The value provided in the Organiozation channel is not being captured in SO_TEAM-Low
Please have a look on the below codes.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR so_team-low .
if not  so_orgchannel-low  is  initial.      "Here so_orgchannel-low  value is coming as Zeros.
select  * from HRP1001 into table GT_HRP1001
          where objid = so_orgchannel-low.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
         EXPORTING
              retfield        = 'ORGID'
              value_org       = 'S'
              dynpprog        = 'ZTEST'
              dynpnr          = '1000'
         TABLES
              value_tab       = gt_hrp1001
         EXCEPTIONS
              parameter_error = 1
              no_values_found = 2
              OTHERS          = 3.
