Hi,

There are many ways

one way is

loop at itab1.

read table itab2 with key field1 = itab1-field1.

if sy-subrc eq 0.

move-corresponding itab1 to iatb3.

move-corresponding itab2 to itab3.

append itab3.

clear itab3.

endif.

endloop.

try one among following :

1)

you can use this:

append lines of itab1 to it_final.

append lines of itab2 to it_final.

....

2)

loop at itab1.

move-corresponding itab1 to it_final. "For same field name purpose

it_final-field1 = itab1-field2. "For different field name purpose

append it_final.

endloop.

loop at itab2.

move-corresponding itab2 to it_final. "For same field name purpose

it_final-field2 = itab2-field2. "For different field name purpose

append it_final.

endloop.

3)

if both the internal tables have same structure you can add

using

append lines of itab1 to itab2. " good performance

hi phanidar

check the code this may helps in clarifying your doubt

TABLES : MARA, MAKT.

SELECT-OPTIONS : SO_MATNR FOR MARA-MATNR .

DATA : BEGIN OF IT_MARA OCCURS 0,

MATNR LIKE MARA-MATNR,

MTART LIKE MARA-MTART,

END OF IT_MARA,

BEGIN OF IT_MAKT OCCURS 0,

MATNR LIKE MARA-MATNR,

MAKTX LIKE MAKT-MAKTX,

END OF IT_MAKT,

BEGIN OF JTAB OCCURS 0,

MATNR LIKE MARA-MATNR,

MTART LIKE MARA-MTART,

MAKTX LIKE MAKT-MAKTX,

END OF JTAB.

START-OF-SELECTION.

SELECT MATNR MTART

FROM MARA

INTO TABLE IT_MARA

WHERE MATNR IN SO_MATNR.

SELECT MATNR MAKTX

FROM MAKT

INTO TABLE IT_MAKT

WHERE MATNR IN SO_MATNR

AND SPRAS = 'E'.

LOOP AT IT_MARA.

MOVE IT_MARA-MATNR TO JTAB-MATNR.

MOVE IT_MARA-MTART TO JTAB-MTART.

APPEND JTAB.

ENDLOOP.

CLEAR IT_MARA.

SORT JTAB BY MATNR.

SORT IT_MAKT BY MATNR.

LOOP AT IT_MAKT.

READ TABLE JTAB WITH KEY MATNR = IT_MAKT-MATNR.

IF SY-SUBRC EQ 0.

JTAB-MAKTX = IT_MAKT-MAKTX.

MODIFY JTAB INDEX SY-TABIX.

ENDIF.

ENDLOOP.

LOOP AT JTAB.

WRITE 😕 JTAB-MATNR,

JTAB-MTART,

JTAB-MAKTX.

ENDLOOP.

While merging there must be key field existing the two internal tables.


either u can create a new internal table and dump the data of the two itabs to it.
or u can modify the primary table(itab1) from the secondary table(itab2)


1) itab1 has field matnr mtart
2) itab 2 has field matnr werks


loop at itab1.
read table itab2 with key matnr = itab1-matnr.
check sy-subrc = 0.
itab3-matnr = itab1-matnr.
itab3-mtart = itab1-mtart.
itab3-werks = itab2-werks.
append itab3.
endloop.

it can be done also like this.

put a field werks in itab1 and modify it.

loop at itab1.
read table itab2 with key matnr = itab1-matnr.
check sy-subrc = 0.
itab1-werks = itab1-werks.
modify itab1 transporting werks.
append itab3.
endloop.


the above statements can be used if u r sure that the inner join condition exists in the tables.


if the itab2 has more than one entries for the matnr in itab 1
( ex: more than one werks for a matnr).

Then use this.

loop at itab1.
Loop at itab2 where matnr = itab1-matnr.
itab3-matnr = itab1-matnr.
itab3-mtart = itab1-mtart.
itab3-werks = itab2-werks.
append itab3.
endloop.
endloop.



reward if usefull :-)

Hi

Simple Use append ines of itab1 to itab2.
