Internal table record checking (Urgent)

Former Member — Fri, 02 May 2008 12:43:48 GMT

Hi Experts,

I have an internal table having records. I want to check each record of the table with every other record to find out if there exist same record for more then one key field.

Can anybody help me to place the logic for how i can check the records with each record? Like

lifnr banks

1 12

2 34

3 12

4 12

5 76

I want to find out 1,3 and 4.

Thanks a ton in advance

Hi Moni,

Try the Below Piece of Code:

DATA:
  jtab LIKE itab.

jtab = itab.

LOOP AT itab INTO wa.
  LOOP AT jtab INTO wa1 WHERE banks EQ wa-banks.
      write:
        / wa-banks.
  ENDLOOP.
ENDLOOP.

Try the Below Piece of Code what it does is Fetches the First record and Compares it with all the other Records:

DATA: w_index TYPE i,
w_lines TYPE i.

DESCRIBE itab LINES w_lines.

LOOP AT itab INTO wa.
  w_index = sy-tabix + 1.
  DO.  
  READ TABLE itab INTO wa1 INDEX w_index.
    IF w_index <= w_lines.
      IF wa-banks EQ wa1-banks.
        write:
          / wa-banks.
      ENDIF.
    ELSE.
      EXIT.
    ENDIF.
   ADD 1 TO w_index.
  ENDDO.
ENDLOOP.

Regards,

Sunil.

Hi Moni,

just try this logic

du_itab[] = itab[] . * store all the table records into another table*

loop at itab into wa. " here one record comes into workarea

read table du_itab into du_wa with key du_wa-number = wa-number.

*( here read command checks in the table du_itab if any same record exits and that record puts into the du_wa)***

endloop.

just try like above u can get..

Hi Moni,

Try this sample code, wherein we can seperate the duplicated records and store them in a seperate internal table.

***************************************************************

LOOP AT it_data INTO wa_data.

index_1 = sy-tabix.

index_1 = index_1 + 1.

LOOP AT it_data INTO wa_data FROM index_1

WHERE plant = wa_data-plant

AND material = wa_file_data1-zmaterial

AND fisc_year = wa_file_data1-zfisc_year.

MOVE-CORRESPONDING wa_data TO wa_data1.

APPEND wa_data1 TO it_data1.

CLEAR: wa_data, wa_data1.

flag = c_01.

IF flag = c_01.

flag = 0.

index_1 = index_1 - 1.

n1_i = n1_i + c_01.

ENDIF.

ENDLOOP.

***************************************************************

Hope this is helpful to you. If you need further information, revert back.

Reward all the helpful answers.

This works


DATA:
  BEGIN OF rec1,
    lifnr(1),
    bank(2),
  END OF rec1,
  itab LIKE STANDARD TABLE OF rec1.
DATA:
  BEGIN OF rec2,
    bank(2),
    count      TYPE i,
  END OF rec2,
  itab2 LIKE STANDARD TABLE OF rec2.

START-OF-SELECTION.

  PERFORM build_table.

  REFRESH itab2.
  LOOP AT itab INTO rec1.
    rec2-bank = rec1-bank.
    rec2-count = 1.
    COLLECT rec2 INTO itab2.
  ENDLOOP.
  LOOP AT itab2 INTO rec2
    WHERE count GT 1.
    LOOP AT itab INTO rec1
      WHERE bank EQ rec2-bank.
      WRITE:/ 'Bank', rec1-bank, 'Lifnr', rec1-lifnr.
    ENDLOOP.
  ENDLOOP.


*&---------------------------------------------------------------------*
*&      Form  build_table
*&---------------------------------------------------------------------*
FORM build_table.

  rec1-lifnr = '1'.
  rec1-bank = '12'.
  APPEND rec1 TO itab.

  rec1-lifnr = '2'.
  rec1-bank = '34'.
  APPEND rec1 TO itab.

  rec1-lifnr = '3'.
  rec1-bank = '12'.
  APPEND rec1 TO itab.

  rec1-lifnr = '4'.
  rec1-bank = '12'.
  APPEND rec1 TO itab.

  rec1-lifnr = '5'.
  rec1-bank = '76'.
  APPEND rec1 TO itab.

ENDFORM.                    " build_table

and the Output


Bank 12 Lifnr 1    
Bank 12 Lifnr 3    
Bank 12 Lifnr 4

Hi Sunil,

Thanks for the reply. can you also tell me that if suppose 2 and 4 is duplicate of 1 and i need to fill a duplicate field of 1 with 2 and 3.

How can I do it?

Means

lifnr banks duplicate

1 xx 2, 3

2 xx 3 etc

Something like that

Hi Moni,

If there exists a third field called Duplicate (of type Char or STRING)and if you want to fill it with the Duplicates, If yes, then try the Foll Code:

DATA:
  jtab            LIKE itab,
  w_duplicate(10) TYPE c.
 
jtab = itab.
 
LOOP AT itab INTO wa.
  LOOP AT jtab INTO wa1 WHERE banks EQ wa-banks.
    CONCATENATE w_duplicate wa1-lifnr INTO w_duplicate SEPARATED BY SPACE.
    wa-duplicate = w_duplicate.
    MODIFY itab FROM wa.
  ENDLOOP.
ENDLOOP.

LOOP AT itab INTO wa.
  write:
    / wa-lifnr,
      wa-banks,
      wa-duplicates.
ENDLOOP.

Hope that was related to your Doubt.

Regards,

Sunil.

Hi,

Use the below logic.

data: begin of itab occurs 0,

lifnr type lifnr,

banks type i,

end of itab.

data: v_count type i,

v_banks type i.

data wa like itab.

itab-lifnr = 1.

itab-banks = 12.

append itab.

itab-lifnr = 2.

itab-banks = 34.

append itab.

itab-lifnr = 3.

itab-banks = 12.

append itab.

itab-lifnr = 4.

itab-banks = 12.

append itab.

itab-lifnr = 5.

itab-banks = 76.

append itab.

sort itab by banks.

read table itab index 1.

v_banks = itab-banks.

loop at itab.

if not v_banks = itab-banks.

v_banks = itab-banks.

write:/5 wa-lifnr, 20 wa-banks, 40 'Count = ', v_count.

clear v_count.

endif.

wa = itab.

v_count = v_count + 1.

endloop.

write:/5 wa-lifnr, 20 wa-banks, 40 'Count = ', v_count.

Actually i have that Duplicate field in the table where I am storing all the matching records. In that case how I can modify that.

When I am filling it with itab-duplicate = wa1-lifnr. where all other fields are initializing with wa then it is doing but not in an ordered manner

Mean in one it is showing 4 and in 4 showing 1.

Thanks for Help Sunil, But Cna you sort this too?

Hi Moni,

IF in my First Reply the Second technique was working then this should solve your Problem:

DATA:
  w_index TYPE i,
  w_lines TYPE i,
  w_duplicate(10) TYPE c.
 
DESCRIBE itab LINES w_lines.
 
LOOP AT itab INTO wa.
  w_index = sy-tabix + 1.
  DO.  
  READ TABLE itab INTO wa1 INDEX w_index.
    IF w_index <= w_lines.
      IF wa-banks EQ wa1-banks.
        CONCATENATE w_duplicate wa1-lifnr INTO w_duplicate SEPARATED BY SPACE.
        wa-duplicate = w_duplicate.
        MODIFY itab FROM wa.
      ENDIF.
    ELSE.
      EXIT.
    ENDIF.
   ADD 1 TO w_index.
  ENDDO.
ENDLOOP.

LOOP AT itab INTO wa.
  write:
    / wa-lifnr,
      wa-banks,
      wa-duplicates.
ENDLOOP.

ELSE try the below code it is same as above except one more Internal Table is used:

DATA:
  w_index 	  TYPE i,
  w_lines 	  TYPE i,
  jtab            LIKE itab,
  w_duplicate(10) TYPE c.
 
DESCRIBE itab LINES w_lines.
 
LOOP AT itab INTO wa.
  w_index = sy-tabix + 1.
  DO.  
  READ TABLE jtab INTO wa1 INDEX w_index.
    IF w_index <= w_lines.
      IF wa-banks EQ wa1-banks.
        CONCATENATE w_duplicate wa1-lifnr INTO w_duplicate SEPARATED BY SPACE.
        wa-duplicate = w_duplicate.
        MODIFY itab FROM wa.
      ENDIF.
    ELSE.
      EXIT.
    ENDIF.
   ADD 1 TO w_index.
  ENDDO.
ENDLOOP.

LOOP AT itab INTO wa.
  write:
    / wa-lifnr,
      wa-banks,
      wa-duplicates.
ENDLOOP.

Hi Sunil,

your first code is working for me. But when I am putting the concatenate stat it is showing

lifnr duplicate

1 2

2 2

4 2

in my case 1 = 2 and 2 = 4 or 1 = 2, 4 something like that

Can you help in this lastly.......?

Re: Internal table record checking (Urgent)

Former Member — Fri, 02 May 2008 14:37:03 GMT

Hi Moni,

I don't think that it will work using First Code because we have used LOOP with WHERE condition so it will take all the Records starting from First to Last.

So for this only Second Code(Technique) can Solve the Problem.

Sunil.
