provided you are looping at itab2.

loop at itab2 into wa-itab2.
modify wa_tab1 from wa_tab2.
modify itab1 from wa_tab1.
endloop.

Hi,

Use

LOOP....

MOVE-CORRESPONDING FROM wa_tab2 to wa_tab1.

MODIFY itab1 from wa_tab1.

ENDLOOP.

Even better is

FIELD-SYMBOLS: <wa_tab1> like wa_tab1.

LOOP.. ITAB1 ASSGINING <wa_tab1>.

MOVE-CORRESPONDING FROM wa_tab2 to <wa_tab1>.

ENDLOOP.

In the second case you dont need modify as its the record of the internal table you are modifying when you change the FIELD-SYMBOL.

Hi,

You need to have same structure for itab1 & itab2.

No need to use work area for itab1 in loop, bcoz there is no modify for wa.

loop at itab2 to wa_tab2.

modify itab1 from wa_tab2.

endloop.

Thanks

hi sanjay

the code is fine now it depends upon how many fields are there in the wa and how many do want to change if you want to change only few then better use TRANSPORTING abc FIELDS

reward if useful

Hi Sanjay,

In the sample code that u have given is absolutely ok. But, thing is that if the structures of itab1 and itab2 are similar, then no need to write the statement "modify wa_tab1 from wa_tab2." and the second Modify statement will become "modify itab1 from wa_tab2.". Now, If the structure of itab1 and itab2 are not similar, at that time u need to specify Elements that whose values you are "Transporting" from one work-area to another work-area. If helpful, reward with some points. Eagerly waiting for your reply.

Hi Sanjay,

u can't modify a work area(in ur case wa_tab1) using a MODIFY statement, u can only modify a internal table using MODIFY statement.

Oops!!! everyone went wrong

try this

loop at itab2 into wa-itab2.
move-corresponding wa_tab1 to wa_tab2.
modify itab1 from wa_tab1.
endloop.

Hi,

"modify wa_tab1 from wa_tab2." stratement is absolutely wrong since we cannot use Modify statement for work-area. So instead of this u can use the statement " Move-corresponding wa_tab2 to wa_tab1". if helpful reward some points.

Opps Please check the code once more:

Wrong Code:

loop at itab2 into wa-itab2.

move-corresponding wa_tab1 to wa_tab2.

modify itab1 from wa_tab1.

endloop.

Correct Code:

loop at itab2 into wa-itab2.

move-corresponding wa_tab2 to wa_tab1.

modify itab1 from wa_tab1.

endloop.
