How to add WHERE Criteria to a Query (SQ01-SQ02)

Question

Hi,
I'm trying to add a WHERE criteria in a query defined by Infoset.
The criteria I want to specify is between two fields of the same table. Something really easy, but ii do not know how to get it.
I think it can be defined in SQ02, but how?
The query should look like the following:
SELECT *
FROM TABLE_A
WHERE TABLE_A-FIELD_1 GT TABLE_A-FIELD_2
Can anybody tell me the secret?
Thanks a lot,
Gabriele

hi,
You can try inner joins on the same table..
select a~WI_ID a~belnr a~gjahr a~INV_ITEM a~INV_DATE a~GR_DATE
  from Z_CPO_GRP as a
  INNER JOIN ZISP_CPO_GRP as b
  on a~belnr EQ b~belnr
  And a~gjahr EQ b~gjahr
  And a~WI_ID EQ b~WI_ID
  And a~INV_ITEM EQ b~INV_ITEM
    INTO corresponding fields of table t_itab
    where a~INV_DATE EQ b~GR_DATE.
  IF sy-subrc EQ 0.
  ENDIF.
