"ON VALUE REQUEST FOR" Activation Error!

Question

Hi All,
Am using a field on my Selection Screen:
SELECT-OPTIONS s_kh_ch FOR p9240-subty NO INTERVALS.
When, am calling an event, to populate the search help for this field:
AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_kh_ch-low.
PERFORM f_call_f4_help TABLES git_subty_9240 USING 'SUBTY' 'P9240-SUBTY'.
It is giving an activation error!
"ON VALUE REQUEST FOR" should be followed by <parameter> or <select-option>-LOW/<select-option>-HIGH.
BUT, For your Information, the same On Value Request For event works well, when i define the field as PARAMETER!
Why is this error being thrown ? Anyone faced this kind of activation error?
Kindly Help...
Thanks in advance.
Rgds,
Sundar.
