ALV Dump error

Question

HI ALL,
              when I try to execute my alv its going for dump throwing the below error.Can anyone help me .
Pls do not send any code samples or any links .
I debugged further to find that
in the include :LSLVCF36
the <ls_fcat>-indx_field is initial.
if not <ls_fcat>-indx_field is initial.
          assign component <ls_fcat>-indx_field
                           of structure <ls_data> to <l_field_value>.
        else.
          assign component <ls_fcat>-fieldname
                           of structure <ls_data> to <l_field_value>.
        endif.
        macro_cell_data_get
          <ls_fcat>
          <ls_data>
          <l_field_value>
          ls_lvc_data-value.
My code is below.

Problem is here...
*TOP-OF-PAGE. <---comment this..
DATA: BEGIN OF t_vbak OCCURS 0,
matnr like mara-matnr,
ERNAM like mara-ERNAM,
END OF t_vbak.
Fieldcatalog merge Function is not Recognizing the Table Definition. Table should be Global. But you mentioned under the Event TOP-OF-PAGE.
