How to Display selected Acivity in Next Tab

Question

Hi,
I have a requirement i added an extra in in t-code IW22,
in that the standard screen tab called "ACTIVITIES"
i have some line items ex:
1 activity 1
2 activity 2
3 activity 3
4 activity 4 in this if i select activity 4 then that activity should get display in my added tab
if i select activity 3 then that activity should get display in my added tab.
but my tab is showing default as activity1 which ever i select.
how to do it ?
ill present the code where exactly the data is picking from standard tab (Activity tab)
select single kurztext from qpct into text_i_4
where katalogart = 'A'
and codegruppe = e_viqmma-mngrp
and code = e_viqmma-mncod
and sprache = sy-langu.
if text_i_4 is initial.
text_i_4 = e_viqmma-matxt.
endif.
if ( cust_aktyp = 'V' or cust_aktyp = 'A' ) and text_i_4 is initial.
"Notifn Change/Display
select single * from qmma into viqmma
where qmnum = viqmel-QMNUM and kzloesch = '' .
loop at t_tc.
select single kurztext from qpct into text_i_4
where katalogart = 'A'
and codegruppe = viqmma-mngrp
and code = viqmma-mncod
and sprache = sy-langu.
ENDSELECT.
if sy-subrc = 0.
else.
text_i_4 = viqmma-matxt.
endif.
endif.
if text_i_4 is initial.
message w537(im).
flag_error = 'X'.
exit.
elseif not t_tc[] is initial.
clear t_tc.
concatenate 'Why' text_i_4 into t_tc-why_quest separated by space.
modify t_tc index 1 transporting why_quest.
endif.
Thanks & Regards
