Finding Sum of grouped lines / Tables EKKO, EKPO

Question

Hi, am using the following tables:
TABLES: ekko,ekpo.
with Inner Join
select ekkobukrs ekkoebeln ekkoaedat ekkobsart ekkoekgrp ekkolifnr ekkowaers ekkowkurs ekkoernam ekpobrtwr
   into CORRESPONDING FIELDS OF TABLE itab from ekko
    inner join EKPO on ekPOEBELN = ekkoebeln.
end-OF-SELECTION.
Basically i want to group the result of this SQL statement by Purchasing Doc (ekko~ebeln) and display the
sum of Gross value (ekpo~brtwr) for the line items of  each Purchasing Doc.
Note: i want the Purchasing Doc to appear one time only in the report
i have tried the following :
select  ekkobukrs ekkoebeln ekkoaedat ekkobsart ekkoekgrp ekkolifnr ekkowaers ekkowkurs ekkoernam sum(  ekpobrtwr )
   into  CORRESPONDING FIELDS OF TABLE itab from ekko
   inner join EKPO on ekPOEBELN = ekkoebeln
WHERE ekkobukrs IN S_bukrs AND ekkobsart IN s_bsart
Group By  ekkoebeln ekkobukrs ekkoaedat ekkobsart ekkoekgrp ekkolifnr ekkowaers ekkowkurs ekko~ernam.
then loop through the ITAB:
LOOP at itab.
write:/ itab-bukrs under 'Company Code',
         itab-ebeln UNDER 'PO-Number',
         itab-aedat UNDER 'Date' ,
         itab-bsart UNDER 'Doc-Type'  ,
         itab-ekgrp UNDER 'Purchase-Grp' ,
         itab-lifnr UNDER 'Vendor' ,
         itab-waers UNDER 'Currency',
         itab-wkurs UNDER 'Rate' ,
         itab-brtwr under 'Gross Value',
         itab-ernam UNDER 'Created By'.
ENDLOOP.
but it is not working with me, am not able to show the result of sum(  ekpo~brtwr ) am getting 0 in all lines
thanks a lot for your help
