Reg alv grid using module pool programming

Question

Dear Friends,
I have a situation where i am using alv grid in module programming where in when i click the total button in the tool bar for any numeric column, the screen goes for a run time error.
I have giving all conditions such as made the column in the field structure of lvc_field_catalog as do_sum = 'X',
still goes for a dump...can anyone throw some hints to do more or the reason behind this and also have not excluded the function code for this total pushbutton while passing to the method set_table_for_first_display
thanks...

hi,
check this up

w_tab TYPE zchangereq.
display field details

SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-020.

p_comp RADIOBUTTON GROUP g1.
SELECTION-SCREEN END OF BLOCK b1.

DEFINE add_field.
&1 = FIELDNAME &2 = HEADING &3 = Key field flag
clear w_field_cat_wa.
w_field_cat_wa-fieldname = &1.
lw_field_cat_wa-ref_table = p_ref_table.
lw_field_cat_wa-inttype = p_inttype.
lw_field_cat_wa-decimals = p_decimals.
lw_field_cat_wa-coltext = p_coltext.
lw_field_cat_wa-seltext = p_seltext.
lw_field_cat_wa-do_sum = p_do_sum.

append w_field_cat_wa to i_field_cat.
