Creating the spool request for the internal table data

Question

Hi..
I am little confused with the function module used for creating the spool request.
well...I am practicing the ALV report and sending the that report to the spool.
I  ve used the FM SLVC_TABLE_PS_TO_SPOOL.
this is the way i defined the internal table.
Data:
begin of imat occurs 0,
matnr like marav-matnr,
maktx like marav-maktx,
matkl like marav-matkl,                     
ntgew like marav-ntgew,
gewei like marav-gewei,
end of imat.
data i_lines type sy-tfill
and i declared..
describe table imat lines i_lines.
then i given the value for i_file_length as i_lines in the export paramet of the FM SLVC_TABLE_PS_TO_SPOOL.
CALL FUNCTION 'SLVC_TABLE_PS_TO_SPOOL'
    EXPORTING
      i_file_length            = i_lines
   IMPORTING
     E_SPOOLID                = spoolid
    tables
      it_textdata              = imat
when i executed it shows the list and wen going back it shows the runtime error as
CALL_FUNCTION_CONFLICT_LENG  - Type conflict when calling a function module (field length).
please provide me some solutions.
thanks in advance.

Hi satyajit,
Thanks for your response....but the fields in my internal table "IMAT" is not compatible with the structure LVC_S_1022 as it has it componenrt - LINE.
so how can i define my internal table IMAT as type lvc_s_1022 as you suggested.
thanks in advance.
