Help in my Logic

Question

See I have this code.
with parameters
PARAMETERS: pdate(6)    TYPE n OBLIGATORY,
            tble1(20)   TYPE C OBLIGATORY,
            tble2(20)   TYPE C OBLIGATORY,
            ccode(20)   TYPE C.
My job is to output a  Report should show all BUKRS, INVNO, sum(WRBTR) and sum(DMBTR) where the sum(WRBTR) and sum(DMBTR)  do not match between Table 1 and Table 2. pdate format is YYYYMM and ccode in this case is the BUKRS field.
This is what I have
SELECT BUKRS BELNR SUM( WRBTR ) SUM( DMBTR ) FROM ZISZT_ZPDPLD INTO zpdpld_line GROUP BY BUKRS BELNR.
           APPEND zpdpld_line to zpdpld_itab.
ENDSELECT.
Now how do I narrow the fields down since I have to take into consideration the ccode, as well as the pdate??

Answer 1

Oh Sorry about that. See I have these parameters:
PARAMETERS: pdate(6)    TYPE n OBLIGATORY,
            tble1(20)   TYPE C OBLIGATORY,
            tble2(20)   TYPE C OBLIGATORY,
            ccode(20)   TYPE C.
in my code. pdate is YYYYMM ccode is optional while table1 and table 2 are the table names. my goal is to output a report that lists the unmatched sum of certain fields in table 1 and 2.
Lets sat field DMBRT AND WRBTR. btw, both tables has these fields. I have to compare the sum of the two tables and output it if there is no match. Now. Before outputting there is a rule. Which is to group them by BUKRS, which in this case is the ccode in the parameter. first i have to group them by bukrs then in the group get the sum and match it with the other table with the same bukrs, if there is not a match, it should be outputted. my problem now is, the pdate. because there is also a field in the table BUDAT with format YYYYMMDD. my pdate parameter is only YYYYMM. I am able to change the table's parameter to match th pdate. but how can i do all these matches?
So far my code is.
SELECT BUKRS BELNR SUM( WRBTR ) SUM( DMBTR ) FROM ZISZT_ZPDPLD INTO zpdpld_line GROUP BY BUKRS BELNR.
          IF ccode+(1) NE ''.
               IF ccode EQ zpdpld_line-BUKRS.
                   APPEND zpdpld_line to zpdpld_itab.
               ENDIF.
          ENDIF.
ENDSELECT.
basically it gets the ccode (BUKRS) the sum wrbtr and dmbtr as well as the document number (BELNR) from the table ZISZT_ZPDPLD(tble1, it always has to be ZISZT_ZPDPLD). Now my problem is, now i am able to group them by BUKRS, able to get the sum, able to compare it with ccode. But how can I compare it with pdate?. I can't make
SELECT BUKRS BUDAT(pdate) BELNR SUM(WRBTR) SUM(DMBTR) FROM ZISZT_ZPDPLD INTO..
since it is not one of the GROUP BY conditions. But I still have to compare it before appending it because it is one of the conditions of my program. Hehe is it clear or not?
