Modify statment is not modifng correct rows...

[Former Member]

Hi All,

iam having ITAB1 with 100 records.Moving corresponding fields from itab1 to itab_final.Itab1 and itab_final have different structure.say itab_final is having 20 fields and itab is having 10 fields.when i move corresponding fields from itab1 to itab_final the respective 10 fields are filled with records.rest of fields(say10) itab_final i need to fetch by some select statment and ineed to do modfiy corresponding fields of itab_final.

-

---

SELECT

KFRST

DATBI

DATAB

KBSTAT

KNUMH FROM A901 INTO TABLE ITAB2

FOR ALL ENTRIES IN ITAB1

WHERE KNUMH = ITAB1-KNUMH.

LOOP AT ITAB2 INTO LS_ITAB2.

ITAB_final-KFRST = LS_ITAB2-KFRST.

ITAB_final-DATBI = LS_ITAB2-DATBI.

MODIFY ITAB_final INDEX SY-INDEX TRANSPORTING KFRST DATBI .

ENDLOOP.

Here My question is how i can find the exact record in itab_final and fill the itab2 field using read statment.

My modfiy statment with sy-index is not modfiy correct row.

Hi,

Before MODIFYING, you will have to first READ ITAB_FINAL by matching the fields from ITAB2 so that you get the correct record.

If the read is successful then sy-subrc value will be 0 and sy-tabix will contain the particular row number of ITAB_FINAL which you want to modify.

So now you can modify using INDEX as sy-tabix instead of sy-index.

Define a work area for itab_final and read that table with the common key fields that you have between those two tables

LOOP AT ITAB2 INTO LS_ITAB2.

*ITAB_final-KFRST = LS_ITAB2-KFRST.
*ITAB_final-DATBI = LS_ITAB2-DATBI.

*MODIFY ITAB_final INDEX SY-INDEX TRANSPORTING KFRST DATBI .
read table itab_final into ls_final with key field1 = ls_itab2-field1
                                          field2 = ls_itab2-field2.
*now 
ITAB_final-KFRST = LS_ITAB2-KFRST.
ITAB_final-DATBI = LS_ITAB2-DATBI.

modify itab_final from ls_final.

ENDLOOP.

Hi Riki,

my itab_final is table type and not having any key fields.So how can i read without key field.

Check any common fields are ther between the two table Itab and itab_final.

else try this way..

LOOP AT ITAB2 INTO LS_ITAB2.
 
  Read table itab_final into ls_final with key field1 = ls_itab2-field1
                                          field2 = ls_itab2-field2.
  If sy-subrc = 0.
     ITAB_final-KFRST = LS_ITAB2-KFRST.
     ITAB_final-DATBI = LS_ITAB2-DATBI.
     modify itab_final from ls_final index sy-tabix TRANSPORTING KFRST DATBI.
  ELSE.
     Move-corresponding fields of LS_ITAB2 to ITAB_final.            "Add this 
     append.
  ENDIF.
 
ENDLOOP.

You cannot MODIFY the records in this manner...

Rather what you can do is...instead of LOOPING ITAB2...you can loop ITAB_FINAL and pass the data...

Check below:

LOOP AT ITAB_final ASSIGNING <fs_itab_final>.

* Read the data from ITAB based on some condition...
<fs_itab_final>-field1 = gs_itab-field1.
....................................................
....................................................

ENDLOOP.

* Now no need of modify, since you have used a field symbol

Sorry got confused by your question.

the solution is as follows.

SELECT
KFRST
DATBI
DATAB
KBSTAT
KNUMH FROM A901 INTO TABLE ITAB2
FOR ALL ENTRIES IN ITAB1
WHERE KNUMH = ITAB1-KNUMH.

loop at itab1 into ls_itab1.

read table itab2 into ls_itab2 with key knumh = ls_itab1-knumh. 
ITAB_final-KFRST = LS_ITAB2-KFRST.
ITAB_final-DATBI = LS_ITAB2-DATBI.
move-corresponding ls_itab1 to ls_final.
append ls_final to itab_final.

endloop.

This will work, no need of modify statement.

Hi,

try this way..

Use SY-tabix not Sy-index...

LOOP AT ITAB2 INTO LS_ITAB2.
 
  Read table itab_final into ls_final with key field1 = ls_itab2-field1
                                          field2 = ls_itab2-field2.
  If sy-subrc = 0.
     ITAB_final-KFRST = LS_ITAB2-KFRST.
     ITAB_final-DATBI = LS_ITAB2-DATBI.
     modify itab_final from ls_final index sy-tabix TRANSPORTING KFRST DATBI.
   ENDIF.
 
ENDLOOP.

Hi ,

Kinly Chk this,

data:
w_index type i.

LOOP AT ITAB2 INTO LS_ITAB2.

ITAB_final-KFRST = LS_ITAB2-KFRST.
ITAB_final-DATBI = LS_ITAB2-DATBI.

add 1 to w_index.
MODIFY ITAB_final INDEX w_index TRANSPORTING KFRST DATBI .

ENDLOOP.
